Forsaken House — Richard Baker

Ten millennia of hubris, betrayal, failure, and retreat are coming to an end.

House Dlardrageth is an ancient cabal of demon-spawned sun elves who burn for vengeance against the elven realms that defeated them long ago.

Araevin is an elf mage from Evereska who discovers Dlardrageth's return and may have to spend his sanity to defeat them.
