Enchanter deity

[pink grapefruit]

I know that enchanters are "supposed" to be agnostic because this allows them to wander freely through all the cities (except Cabilis?) without issue. But if a person did pick a deity, say Tunare or Quellious, how exactly would it affect them? Would Stein quest be impossible? Would you be prevented from banking somewhere, or buying your spells?

Agnostic always seemed so boring.
