is there a DW bestiary or is it the Dark heracy one

Hi,

have a look at the upcoming: www.fantasyflightgames.com/ffg_content/deathwatch/minisite/support/litany-of-war.pdf

Hopefully we will see the Mark of the Xenos in Spring 2011.

Since then you can simply refer to the Creatures Anathema for DH.

Cheers,

TechVoid.
