Yarshag

The powerful druid lizard that headed the Dark Talon Lizards for many years. He claimed to have slain a black dragon and used baby dragons and evil chaositech to breed super-strong lizard soldiers with which he then proceeded to conquer the south of Dangerous Jungle.

In the end he was stopped at the Battle of Charging River by an alliance of woodfolk, elves, men, undead, flying monkeys and kobolds. At the end of that battle, the blue dragon Grizzicckk destroyed his reserves and forced him to hand over his magic black dragon plate armor and the Greatsword of Swampfire.
