Amareth Faith (Zyanya Supplement)
From D&D Wiki
The Amareth region follows the god Samad. They consider all other gods to be either aspects of Samad, or daemons posing as gods.
Samad is the god of everything, of good, of creation, etc….
Though he is Lawful Good, he can be worshiped by any alignment.
The dirty secret of Amareth is that the old one known as Usezel, formerly the patron of evil, still exists and can still grant spells. In fact, the victory of Samad over all the remaining old ones actually increased his power by allowing him to take over any domain that Samad did not possess. Usezel is Chaotic Evil but can be worshiped by any of evil or neutral alignment.
