The game features a unique system of reputation.

You will be outlawed if you are caught stealing,pickpocketing & attacking citizens in Callaheim and any other villages and outposts.

Every citizen,trader,man,woman & guard will attack you on sight screeching curses.

The exceptions are ruffians in west Callaheim who will attack you at night no matter you are outlaw or not (sometimes they don't if you are,if they don't simply provoke them, they are a good sport).

To restore your reputation speak to Quentin in Callaheim sewers who will do so at a hefty price depending on your level. He will also change the stance of ruffians and thieves to neutral (at a price of course) so that as rogue you can visit the Thieve's den to buy poisons.
