I just read the new story in that compilation Heroes of the Space Marines about the Sons Of Malice and their worship of that god. Anyone who has read it think that there may be a resurgence of him in future fluff. The ending definately leads one to think something big is going to happen in the near future. What do you think it might be? The Sons are only a chapter size in strength, what can they do against every else, everyone else being the Imperium and Chaos.
