Madness seeps into the Valsollas Galaxy. Born in the black flames of planetary genocide, Cascius Carcyde rose from the ashes with a gifted mind and hardened himself into the most renowned scrutineer across the Velutra. For two centuries, he has solved impossible mysteries while hunting the foul subjects of Malnetha who murdered his homeworld, all at a terrible cost. Cascius' addiction to reliving his sorrows has almost claimed his life. But when the Sages demand he take a new partner-a young illuavan named Kirella-Cascius must forfeit his destructive ways to catch the elusive Red Hand killer. As the ocean of dissolved victims swells, the scrutineers uncover a larger machination at play, one they must stop before the entire Velutra falls into oblivion.
