The cult can be undivided, but because of the large amount of psykers on the planet, it would probably have a more Tzeentchian focus. The cult would have most likely have been seeded by an Alpha Legion group nearby, this means that my chapter is fighting a multiple side battle, the alpha legion, who attack at their supply lines and then disappear, and the cult and tzeentchian forces on the planet. This is where another space marine chapter and or Imperial Guard force comes in to help.
