Khameril is a diverse land, so nearly all types of characters can be found, although some are somewhat rare.
In general, magic users are more rare in Khameril than in other campaign settings. This is mostly because every magic user is legally required to be a member of the Covenant of Mages. You can play a magic user that is outside of the Covenant, but you will be an outlaw mage. Note: druids are not welcome in the Covenant, so all druids are forced to live outside the law.
