You can get drunk in various places, and get random scenes. If you do it at the pub (where you met the vampire), you can eventually get in trouble with some guards. There are drugs and mind control in that series of scenes. In temples 2-3-4 you can find hidden statues which can hypnotize you a bit. During a quest you can get in Rahib, you have to visit a temple, and the leader there can hypnotize you as well (although she doesn't have a lot of content).Sorry for my bad english. It is just very difficult. I wanted to ask who else could hypnotize me. I found vampires, cows, 2 scenarios of Sonya, Kira, a hypnotist. And a few more mini stories. 1 in the solina, and several with an amulet. Who else can. You say you can become noble, how is it? Is it necessary to find the missing son of a nobleman? Are there hypnotists in Rahab? And there was some girl when I found the son of a nobleman. She used magic and broke the wall. can she hypnotize me?
Yep, you need to find the missing son. You then need to go meet the Emperor (the noble you helped left a guy in the mage guild who can take you there).
To be honest, though, I can't reply to all your questions (I'd spend all my time here, rather than coding the game XD). I hope someone else will continue helping you, or that you'll start finding your way around more easily.
