If someone's wearing holy symbols of Clar Banda or Bane -I am- going to assume they're evil.
There's books everywhere about these gods.
Also, I -reaaaaaaaaaally- don't understand why the warden or the king or whoever makes the law decision did not ban the worshiping of evil gods by law. If I would play a paladin of Tyr I would call Arabel and Cormyr protectors of evil. It simply doesn't make sense. Worshipping Clar Banda, Bane, Cyric, Shar, should be something hidden in old town or hidden inside the citadel, not openly shown.
Just to explain my point.. how can what follows be allowed to be worshipped inside the spire of the citadel, by any logic?
In 1379, it is known that Banda through some unholy ritual gained deityhood through the sponsorship and aid of Shar near the region of the Stonelands at the edge of the Anauroch Desert. The ritual is believed to have consumed the souls of hundreds of people slain in plagues and disasters Banda perpetuated against the region of Arabel and the now cursed village of Hallowfaust; once called East Way and a thriving farming town.
SETTING-SPECIFIC HISTORY: Banda was a long time enemy of Arabel
