Hello! I'm a semi-experienced player that's looking for a campaign that's accepting of homebrew races. I ask this because I want to play a Paladin of a homebrew race I've got in mind, but I lack the proper Oath (that being the Oath of Vengeance). 

This is my character, Mahesh Ironfang, Saurain Tyriul.

"The son of the Red Emperor, heir to the Ceracati throne, brave Paladin, what more can be said about Prince Mahesh? He has been training in combat and the arcane arts for as long as he can remember, learning from his father, Emperor Virochan, and learning at the Ceracati University, studying under the Wizard, Professor Avaros Stronghorn. But after a terrible dragon laid waste to his kingdom and killed hundreds of Saurians, Mahesh was on the brink of death. Just then, he was visited by He'lia'n, Saurian God of the Sun. He granted the young prince the power to fight back. With boiling blood and blistering rage, he slew the dragon. Now, as a Paladin sworn to the Oath of Vengeance, he requested the ability to venture out into the world. And he has just received his father's approval."
