Gothic 3 BRAGA: Abbas, the water vender

I no sooner step foot into BRAGA and I'm being attacked!
I don't even have a chance to talk with the water vendor.
What did I do to make them attack me?

You probably liberated too many Hashishin cities (and talked to various Hashishin leaders about it), making them all hate you.

Actually, I found my error. Abbas was actually (North of the town) and not in the (North part of town). Sorry, thanks for the quick reply.

Ooops! I spoke to soon, I talked with Abbas and went with Tufail to kill Malir and his bandits. Afterwards I returned to Abbas, told him I got his chalice. Then I went to town to talk with Nafalem, and give him the chalice and he attacks me. It ends up I have to kill everybody except Diego! Like i've said before I really like the game, but it's so screwed up. I guess i'll just go hunting with Diego and continue on.

Somehow I killed a guard outside BRAGA walls and someone else and everything quited down and then I was able to talk to Nafalem and finish the quest.
Really strange! This game is really unpredictable!
Thanks for the help.
