Gersemi

Custom gear for the Guys Being Vikings server.

A gersemi is a treasure, something kept and handed on rather than spent. This mod is where the server's own items live.

The Muspelhelm

A horned war helm, made to mark the 2026 server launch.

A blackened iron cap under a gold brow band that sweeps down over the eyes, with two ridged horns swept up and back. While you wear it the horns burn along their whole length and throw embers that cool as they rise. The band glows faintly and a small light at the brow means the helm casts a little of itself at night.

It gives no real benefit. One armour, the same as a cape, so wearing it is neither a penalty nor a shortcut. It never breaks, cannot be upgraded and cannot be sold.

Forged for the first landing of the Guys Being Vikings, in the year 2026. The horns still carry sparks from the fire the world was lit with.

Worth nothing in a fight. Worth something to whoever was there.

How to get one

They are handed out. There is no recipe and nothing drops one, so ask whoever runs your server.

Using the look on another helmet

If you have Huskarl, holding a Muspelhelm once is enough. Any Guise trader will then offer its look for any helmet you own, so you can keep your real armour and still wear the horns. The fire comes with it, and other players see it too.

Install

Install on the client and the server both. The helm is a custom item, so a machine without Gersemi cannot make sense of one lying on the ground and it will disappear when the area reloads.

The fire

Four colours are available, set with Colour:

Ember	white-hot to orange (default)
Muspel	blue-white
Wyrd	green
Draugr	violet

The helm can also borrow its fire from one of the game's own weapons. Set BorrowFrom to a weapon's name, or to any to use the best one your install has. A borrowed effect is recoloured to match your chosen colour unless you turn Recolour off.

Settings

Setting	What it does
Colour	Which of the four colours the fire burns.
BorrowFrom	Take the fire from a named weapon, or any. Empty uses Gersemi's own.
Recolour	Whether a borrowed effect follows your chosen colour.
Rate	How much fire. 1 is the shipped amount.
BorrowBrightness	Lower if a borrowed effect looks washed out, higher if it looks thin.
BrowGlow, BrowLight	The glow in the band and the light at the brow.
IronColor, TrimColor, HornColor	Repaint the helm itself.
Fit	Adjusts how the helm sits. You should not need to touch these.

To use your own model, put an .obj or .glb named muspelhelm in BepInEx\config\Gersemi\.

Credits

Built for Guys Being Vikings. The helm's shape, its icon and its own fire are generated by the mod; no artwork is copied from Valheim or any other mod. A borrowed effect uses the game's own particle art at runtime on your own machine, and none of it is redistributed.
