Leanatim

Leanatim was a powerful wizard at the height of the Aasimar culture. They relied heavily on the blue sand powering their magic. The Aasimar were particularly resilient to the influence of the Great Beast, but eventually they started to give in to its influence. The first few who fell were stopped, but Leanatim became its ultimate weapon. Leanatim became a serial killer who targeted the most powerful wizards of his people. He would then bring them back as zombies. Eventually he amassed an army of zombies large enough to wage open war on his own people. He lead his zombie army to slaughter any Aasimar that wouldn't fall under the control of the Great Beast.

The fall of his people was several millennia ago. Thanks to the power of the Great Beast Leanatim is still youthful. He still rules as king of the Aasimar, even though the only Aasimar left are his zombie minions.

Leanatim will be friendly to any magic users he comes in contact with, and will try to force them to become his apprentice. His ultimate goal is to bring more people under the control of the Great Beast by encouraging them to use the Blue Sand. Any who refuse him or are incapable of magic will be killed to join his zombie army.
