Arin

Arin is the prophet whose teachings served as the foundation for the Ariden religion. She was the prophet of The Thirteen, the beings whom the Ariden worship.

Background
Arin was a woman who rose to greatness, first as a slave to the Tiber Empire, then as a prophet and religious icon.

According to Ariden scholars, Arin was born a slave in the Tiber Empire and eventually sold to a temple in the capital.

Church of Highcliff
The official belief of the Church of Highcliff is that Arin wasn't the chosen of the Thirteen, but rather "just" a philosopher, teacher, and leader.
