Orc Gods
Not much is known of the Orc gods of Alusia, most philosophers don't want to know.
They have gods, many of them seem to have different names depending on who you ask or maybe they have a lot of gods. Most of them are credited with being progenitors of the Orc race and the most powerful of all gods, the veracity of this often leading to conflict between Orc tribes.

Sezelrian the Fire God
Legend has it that long ago, Sezelrian gifted the Orc race with intelligence and magic. It is said that his followers thrived and grew to a great nation challenging the older established nations of the time (presumably Dwarves & Elves). Subsequent conflicts lead to the annihilation of this great kingdom and the systematic extermination of all of his priests and followers.
In the millennia since, Sezelrian and his great nation have been forgotten amongst the civilizations of Alusia.
Followers of Sezelrian tend to become more intelligent, use magic, fight cleverly, and revel in vengeance.
He teaches the need for intelligence in addition to strength to control fire and magic but has no patience for knowledge without immediate or practical use.
