I don't normally mess with the names of the Fallen that we don't have a description for, since we have no way to tie their form with their potential aspect of creation.
But with all the speculation on Varthiel, I took a look, and found a few things.
- Var, from Dutch, meaning "male pig; boar". Would most likely have a menacing boar-like form.
- Var, from Serbo-Croatian and Czek, meaning "heat" and "boiling" respectively. Would most likely have a fire/heat based ability, with a form that might literally bubble like hot tar. Might be scalding at a touch.
- Var, from Hungarian, meaning "scab". Would most likely be a nasty scab-covered form with oozing blood and puss, but not sure how combat-worthy it would be. There are ties to scab diseases, but those seem limited to potatoes.
