Alright, so my players have boarded a Space Hulk in the Screaming Vortex. Now one of my players, he plays an Apostate who is a very powerful sorceress (used DH rules because psykers and sorcerers are two different thingsmechanically and narratively, despite what BC says) and he wanted to know 1: Is there a way to lock a Space Hulk into a stable orbit of some sort and prevent it from taking another joyride through the Warp? and 2: Is there a way to purge the remaining Warp Influence from the Space Hulk? #2 mostly came about because a large portion of the Medicae Bay in the Hull they're inhabiting actually is flooded with blood.
Any ideas?
For Reference, I did build the Space Hulk using Ark of Lost Souls.
