Aided by the unleashing of demons and an undead elven sorceress, an elvish cult strives to revive the secrets of dark elven sorcery. Outmaneuvered at the Elven High Council, two elves break generations of isolation and seek the aid of outsiders. What part will the Warders play as the ancient elven verse known as The Demon's Debt reveals its true meaning?

Evil behind a doorway barred; three were chosen to serve as guard

Taken from the surrounding wood; their souls entombed in trees they stood

When one shatters birch, fir, or oak; banshee's vengeance visits mortal folk

No hero from the children of light; prevails against the blood moonlight

Summon outsiders into the maze; to stand against the ancient ways
