Charybdis outpost final mission choices??? ***spoiler***

[Sichr]

The wording of the quest is so horrible, that I dont know which option to choose to apprehend the sorcerer. Can you please un♥♥♥♥ this and clarify the outcomes of each of three choices:
1) Apprehend the psykers (but not sorcerer)
2) destroy the chamber
3) preserve the psychioc constelation (wtf this means?)

I chose to destroy the chamber. It killed the sorcerer but opened a warp rift. You get a mission to cleanse the station of three nurgle nests.

In case anyone else is looking for an answer to this still, if you choose the third option to Preserve the Psychic Constellation, it will result in capturing the Sorcerer.
