The Dark Path

Mind control? I'm afraid you have come to the wrong person. Studying something that has been studied thoroughly by generations of psionicists is useless. You could go straight to them without wasting my time.
If you're interested, though... One of my subordinates, aoidos Imperius, is using the data in question in his research. He's a member of the expedition to the Citadel's deepest levels. It's been a month since they departed.
Speaking of which... you might have arrived just in time.

I'm very busy. Leave me alone.

I wish we had copies of Imperius's research... Every demonologist keeps their knowledge secret. Your only option is to find him yourself. You have my permission for an expedition.
