D&D 5E citadel of the planes - thoughts?

Treat those alignment changes as you would the petrification/save-or-die effects, and make sure the characters/players are aeare of the consequences beforehand. I radical, forced change in PC alignment is the equivalent of character death, no? So, as a DM, do what yoy would do in that situation.

I'd be all over a campaign set in this place. It would be cool to start the PCs as custodians of the citadel, perhaps caretakers for some unknowable planar being. I love weird adventures like that.
