Dark Heresy Game Master's Kit (2nd ed, 2014), p22 — Further Adventures

The Callers of Sorrow: In addition to information on the Trade Sable, captured cultists and details from Ferrue's notes indicate that the Blessed Flesh was only a splinter of a much larger cult. Even if the Acolytes do not fully realise the extent of this greater cult, the destruction of the Blessed Flesh draws the attention of the Callers of Sorrow, and it might begin actively targeting the Acolytes. Finally, the GM can include a holo-pict to be found on Ferrue's person, showing him with his two brothers. The Acolytes easily recognise Tormus Fayne if they met him in Gantry, and he is certain to become a major threat in future adventures.
