Triggering the Kaernk in the Cistern?

[Atganos]

Is there something you have to do to trigger this event?

You should have low sanity, that's what triggers Shadow and the Kaernk.

Hmm, I shall try that then. Thanks. Do I need to have low sanity when I hit the last valve?

Did it happen you went into the morgue before going into the cistern because that mostly triggers the Kaernk to appear.
