Skirting dangerously close to the edge of what the Inquisition deems a proscribed work, the Crimson Bestiaries, is a useful Xenos reference guide that is packed with illustrations, photos, and text in a number of Xenos-related topics. This particular copy was secured by a Deathwatch Kill-team, on orders of Inquisitor Sand, who raided the base of an ork named Greenhorn on the planet of Ganf Magna.

Using a Crimson Bestiary requires a successful +0 Literacy Test. If the test is successfully passed, a character using the tome to learn something relating to the Calixis Sector and the surrounding stars gains a +5 bonus to his next Forbidden Lore (Xenos) Test.
