Abraxis

The Great Dragon God of Conflict and Destruction. Defeated long ago by his rival the Starcaller so that creation could prosper, his mortally wounded essence was sustained by a cult of draconic followers who thought to bring about his return. During a deadly ritual a young Monk stole a small portion of Abraxis's sacred blood and drank it to gain power. This process nearly destroyed this man who would one day become Abraxis's disciple and chosen warrior. Abraxis tested this Monk offering power alongside lessons of how struggle and conflict can lead to growth and how the victor had the right to guide destiny. This Monk would one day become Relis of the Obsidian Guard and they would one day embark on a quest for the Heart of Tides in exchange for an army to confront the Black King in his Abyssal Stronghold over the Ocean of Blood. The Heart of Tides, was the Core of a Planar Lord and it empowered Abraxis enough to break through the Divine Gate and reclaim his divinity.
Since his return his religion has enjoyed a resurgence among soldiers and warriors as well as the Dragonborne and monks.
