Silent and ruthless killers, the Dark Elves are a notoriously deadly race. Whether a Dark Elf is born Blue, White, Green, Red, or Gray, their true nature is revealed within just a few years. Impulsive and temperamental, Gaw'er has never fit in with the other Blue Elves. When his true nature comes to light, the young elf is taken from his family to begin a long and painful apprenticeship with the Dark Elves.

In response, Aamon sends renowned detective team Lanawyn and Turin to lead the investigation. Will the duo be able to figure out what’s slaughtering Aspen’s greatest warriors before it’s too late?
