Le'var Elves

Le'var Elves (often referred to as Thelvi, or simply Le'var) are a humanoid race that lives in the Le'var province of Tragulus. They were originally the same as Duemeran Elves, but deliberately split with them shortly after the Human conquest of Tragulus.

Biology
The primary differences between the Le'var and the Duemerans lie in the former's pale, almost deathly-white skin, red eyes, and their elongated ears. These changes are purely cosmetic, and they are fully capable of reproducing with Duemeran Elves.

Le'var are also highly resistant to natural and plant-based poisons; while most of this is due to ritual mithridatism practiced since birth, it has also become a natural feature of many of them.

Relation to Vampires
The physical characteristics of the Le'var match almost exactly with those of vampires. Though it is indeed possible that they are somehow connected, especially considering the Le'var's reputation as dark sorcerers, no links between the two have been confirmed.
