In the Murkmire Malevolence, Doctor Horthnar attended Alda Arkin's gala, spending time with the eager Rasmus O'Dranith. Not realizing he was speaking to a thief, Horthnar identified gemstones and taught the Unknown about the secret animation behind the Allosaurus Skeleton.
The night dissolved into chaos after the appearance of Caelas Helefir and Ulre Helefir, and Horthnar was forced to flee the gala.
