What happens to NPC's with 100 corruption?

By Lockark, in Black Crusade

I can't seem to find in the book were what happens. Do they turn to chaos spawn? If thier imperals do they fall to the lure of chaos?

=O

Any page numbers to point me in the right direction will help. thanks.

Minor NPCs turn to spawns when they hit 10 CP. I don't think there's any other mention about that in the book, though I've only skimmed it.

Well. That's a start anyway. thanks!
