⛈️ Ragnarok's Wrath

The land remembers who walked it.

The world reacts, and it remembers.

Seasons turn, storms rage, plague takes root and creeps, fire leaves scars, farmed soil tires, the wild wages war on the blight, and the land holds grudges against the people who hurt it, then raises stone monuments where its stories end. Every zone quietly keeps score of what has happened there, across restarts, forever.

There is no tracker, no dashboard, no HUD. The world tells you itself: a sickly fog in a blighted valley, ash drifting over an old burn scar, a deer that staggers, a bush that refuses your hand specifically, runes glowing on a stone that remembers a fire.

This version is the Valheim 1.0.21 build. Nothing else is new.

You	It
Play on Valheim 1.0.21	the mod is rebuilt and checked against it; the gameplay is unchanged
Update the server and every player together	Valheim 1.0.21 moved the game's network version to 41, so a server and its players must all be on the new game: update the mod on all of them at the same time

---

	If…	Then…
🤝	you play on a server	install it on the server and every player: the same DLL does both jobs. A player whose version differs from the server's is warned once on screen, and features quietly stop showing until they match.
🔥	you install by hand	install FireFront (Raven Iron) too, and keep it current. Mod managers bring it for you. Without it, fire scars, arson and storm lightning sleep; everything else runs.
⚖️	you change the config	give every player the same values as the server. Many gameplay settings act on each player's own game, so a player with a different file plays by different rules on the same world. The visual effects are the exception.
☁️	you play single player on a Steam Cloud world	the land's memory lives beside the local save and does not travel with the cloud: move machines and the land starts fresh. Dedicated servers and local worlds are unaffected.
🧪	you want to know how finished it is	every system is live and checked on a dedicated server, most rates to four decimal places against prediction, but it is an early, evolving mod. Report anything strange: the logs are chatty in all the right places.

---

Spring, Summer, Fall, Winter: they change how the world plays, never how it looks.

🍂 Gameplay, not paint	plague growth, frost, farming and how fast burnt land heals all swing with the season
🔄 One clock, never two	runs its own clock, or uses the season from Seasonality or Seasons (shudnal) when one is installed

---

Real vanilla events, with banner, music and timer, on the wrath's own schedule.

⛈️ Positional	a storm has an area: plague spreads faster inside it and nowhere else
⚔️ It feeds the war	a storm over contested ground escalates the fight beneath it
⚡ It can strike	with FireFront, a rare bolt lands near someone under the storm and starts a real fire: never in rain, never near anything player-built
🌤️ The sky stays yours	by default a storm never touches the sky, so it never fights your weather mod

📖 Read the saga — giving a storm its own sky

A server that runs no weather mod can turn on StormsForceWeather. Each storm then rolls wet or dry: the wet sky brings rain, which stops lightning; the dry sky is dark and thundery with no rain, and it is the warning that this storm can start fires. Every player needs the same value and a full restart of the game to see it.

---

A spreading, curable sickness that lives in the ground, and then in you.

🦠 It starts on its own	every so often an outbreak quietly takes root where people live and walk, likelier on corrupted or burnt land, carried by storms
🐛 It creeps	it grows where players linger, spreads along its frontier, feeds on corruption, rides storms, and dies back through winter or neglect
🌫️ You see the land go wrong	a grey-green miasma where it runs deep: no marker, no map icon
🤒 It gets into you	stand in it and exposure builds over tens of minutes into a real sickness, stamina first, then healing, shown as a vanilla status icon
🍯 You can shake it	leaving drains it, rest drains it faster, poison-resist mead slows the intake. Relogging is not a cure
❄️ The cold bites too	on high-frost ground you are chilled where vanilla would not call it cold, and your breath fogs; a campfire or frost-resist mead answers it

---

With FireFront, a fire chars the land itself.

🔥 Scorch	burning zones gain scorch, which holds back recovery and outlives the flames
🌋 Ash	grey ash drifts over old burn scars, thinning as the land heals
🕯️ Arson has a name	FireFront tells the wrath who lit each fire, across its whole spread

📖 Read the saga — why FireFront, and what if it is missing

FireFront owns every flame. Ragnarok's Wrath ships no second fire simulation: it reads where FireFront is burning, records the scorch, and asks FireFront to light what storm lightning strikes. FireFront is a dependency, so mod managers install the pair together.

Without FireFront the fire systems sleep. An older FireFront does not error either: a feature it cannot reach is simply never reached, and the log names what it could not find, at boot or the first time it looks. Keep FireFront current for all of it.

---

Sick land acts like it. Tired land grows slow.

🌱 Tired fields	fertility tires under dense crops, and crops in depleted soil take up to twice as long, so resting a field genuinely pays
☠️ Corruption	blighted and burnt ground corrupts, and corruption feeds the plague
🫐 Barren ground	berry bushes and mushrooms stop yielding on plagued or burnt ground
🦌 Sick wildlife	animals stagger visibly sick
🥀 Withering crops	crops in deeply blighted soil wither and die
⭐ Meaner spawns	creatures born on corrupted ground come up starred
🌍 The world's condition	Flourishing, Stable, Ailing, Stricken: the world judges itself and announces the turning points to everyone

Player structures are never touched.

---

Every act is remembered, per zone, per player.

🌿 Care	planting and a healing presence book care; tended ground heals faster for its keeper and sheds their sickness sooner
🔥 Harm	arson books harm to the arsonist by name
😠 Grudges	grudged ground drifts harsher under your feet, refuses you berries it gives freely to others, and marks you Ashbringer
🏅 Standing	regional standing earns Warden or Despoiler
⚔️ Spawn wars	where blight and genuine care collide, the zone goes to war: the blight's spawns star harder, the wild pours in to answer, storms escalate it, and it ends one way or the other with a single line to whoever stands there

---

The creature that kills you is marked in that moment.

⭐ It grows	it gains a star, and its nameplate remembers: slayer of Nomad, counted on repeat offences
👑 Bosses too, fairly	a boss is marked but never gains a star: its health bar carries the name, and the fight stays the size it was built to be
💾 It remembers	the mark lives in the creature's own body and survives server restarts. If it despawns, it got away
🗡️ The only cure	kill it

---

The world writes its own monuments.

✨ Blessed stones	a great fire fully healed, a plague driven out: blessed ground heals quicker and sheds sickness faster
🩸 Cursed stones	a war lost to the blight: cursed ground sickens you and breeds meaner things
🗿 The rare one	the land recovering from Stricken raises one rare stone on the ground that healed the most
ᚱ Glowing runes	standing stones wear runes, gold or blood-red
🔨 Vandals	the stones can be broken, but the land books the vandal, and it does not forget

---

Earned from what happened to you, never from tracked stats.

⛈️ Stormrider · ☣️ Plaguewalker · ❄️ Winterborn	caught in a storm, stood in badly plagued ground, lived through Winter
🔥 Ashbringer · 🌿 Warden · 💀 Despoiler	lasting harm or care to the land

The latest title earned shows under your nameplate.

First ten minutes: install it with your mod manager on the server and every player (FireFront comes with it) → play; there is nothing to press → type wrath status in the console to see the world's state → walk into a fog and feel it.

Command		Where it runs
wrath status	the world at a glance	anywhere
wrath zone [x y]	one zone's full story, underfoot when you leave out x and y	anywhere
wrath relics	peaks, stones, pending, era	anywhere
wrath zone set x y field value	set a zone's fert, corr, scorch, frost or plague	on the server (admin)
wrath care set x y playerId value · wrath harm set x y playerId value	set one player's care or harm in a zone	on the server (admin)
wrath save	write every store now	on the server (admin)

Typed in game by an admin, the server commands go through vanilla's own admin gate, run where the world lives, and reply to your screen.

🛠️ Fix a zone by hand

Stand in the zone and type wrath zone to read it, then wrath zone set x y field value with a value from 0 to 1. Server owners never need to hand-edit a save file, though they can: every store is plain tab-separated text.

🛠️ Keep players on the same rules

Copy the server's two config files to every player: com.raveniron.ragnarokswrath.cfg and com.raveniron.ragnarokswrath.advanced.cfg. The settings marked below as read on each player's own game must match the server; the visual effects need not.

---

Works with vanilla players and servers	Needs it on the server	Needs it on both ends
no: install it on the server and every player	the simulation and every zone's memory · storms and outbreaks · relic stones · the world's condition and announcements · the server commands	the miasma, ash, frost breath and runes · sickness and chill · tired soil · the land's consequences · grudge-refused picking · spawn wars · the nemesis · relic auras

Versions should match. The server runs the simulation, and each player's game shows what it pushes and acts where that player stands. If the server and a player disagree about the mod's version, the player is warned once on screen; mismatched pairs fail safe, but features quietly stop showing until they match.

---

Mod
FireFront	A listed dependency, installed with it by mod managers. It unlocks fire scars, arson by name and storm lightning. Removing it is safe: those systems simply sleep.
Seasonality · Seasons (shudnal)	Found and used by themselves: their season drives the wrath, and it runs no clock of its own.
Weather mods	A storm never touches the sky unless StormsForceWeather is on.
AwayFromHome	Deliberately compatible: drift never ticks on zone load state, unattended bases never burn, and sweeps are staggered off its rescan.

The mod adds no prefabs, no assets, no bundles: every visual is generated in code, on purpose.

---

Two files in BepInEx/config/. com.raveniron.ragnarokswrath.cfg holds every system's on/off switch and the settings most servers change; com.raveniron.ragnarokswrath.advanced.cfg holds the tuning (rates, thresholds, intervals and lists) under the same section names. Every setting has a plain description in the file. Close the game or server before editing; changes apply at the next start. Nothing is synced: each machine reads its own files.

🔒 On the server — the server's own file decides

Section	Setting	What it does
02 - Season	EnableSeason · SeasonLengthDays · AnnounceSeasonChange	the season clock, its length in game days, and the message when it turns
03 - Weather	EnableWeather · StormMinIntervalSeconds · StormMaxIntervalSeconds · StormDurationSeconds	Devastating Storms, the shortest and longest gap between them, and how long one lasts
03 - Weather	StormDryChance	the chance a storm rolls dry instead of wet
04 - Biome state	EnableBiomeState	each zone's slow drift and healing
05 - Fire	EnableFire · StormLightningEnabled · LightningMeanMinutes	scorch from FireFront's fires, storm lightning, and how rare a bolt is
06 - Plague	EnablePlague · PlagueGenesisEnabled · PlagueGenesisMeanHours	the plague, outbreaks that start on their own, and how often
07 - Ecology	EnableEcology	land corruption
10 - Consequence	AnnounceConsequences	the one-line message when you enter sick ground
11 - Rivalry	AnnounceContests	announce a contested zone changing hands
13 - Titles	EnableTitle · AnnounceTitles	earned titles, and the message when one is earned
14 - World state	EnableWorldState	the world's overall condition
15 - Visuals	EnableZoneSync	send zone state to players, which the fog, frost breath and ash need

🖥️ On each player's own game — keep the gameplay ones the same as the server

The same on every player as on the server:

Section	Settings
03 - Weather	StormsForceWeather · StormForcedEnvironment · StormDryEnvironment (a storm's own sky, wet and dry; needs a full restart)
08 - Farming	EnableFarming
09 - Health	EnableHealth · FrostChillEnabled
10 - Consequence	EnableConsequence · ConsequenceBarren · ConsequenceEmpower · ConsequenceSicken · ConsequenceWither
11 - Rivalry	EnableRivalry · EnableNemesis · NemesisMaxLevel
12 - Relic	EnableRelic

Yours alone:

Section	Settings
15 - Visuals	PlagueFogEnabled · FrostBreathEnabled · ScorchAshEnabled · RelicRunesEnabled
01 - General	VerboseLogging (a log line for every pass of every system, on whichever machine turns it on)
