Prince Bekbahael who ended up lasting around 6 years even with both his heads decapitated, due to the placement of his horns (or what ever they are???). Tho after Bekbahael lost his heads he was practically just a quivering corpse who's only source of life came from thE ORB.
He's looked upon as the best and strongest price (for obvious reasons) so there's a huuuUUUGGE assed statue of him that's carved around a waterfall close to one of the major cities. Many people go there on a daily basis to pay their respects and worship him

i really need to flesh out this world a lot more < : /
