I'm surprised that so many people chooses Cheydinhal (even over that dirty pathetic and smelly slump that is Bravil), only because there's a DB base there. What's the point? They're a "public service", after all. I don't see any reason they'd start mindless slaying all the people in the town. And if you've been targeted by them, they're gonna find you and you'll have a fight with them anyway, regardless of where you live. Besides, I don't think Bravil is any safer than Cheydinhal....pretty much au contraire.
Believe me, if people could really have a try and live in Bravil, they'd gladly change it for Cheydinhal in 3 days
