Ah yes, another one of Dral’s brothers/ Godroth’s creations! This beautiful fellow has a horde of souls that he reaped during the war time. The only reason he rebelled to begin with was because he grew tired of feeding the dead to his maker aka Gordo, so he went off to do his own thing before he too was locked away, though underground. Though interestingly, he had escape to retrieve his horde of souls before going underground on his own whim, which means that he is free to leave at any moment, but he doesn’t. It is possible to visit him at any given time if you manage to find his crystal cave. For an offering of gems or any jewel/something of wealthy nature/a soul, he will do a favour, but he answers questions for free. Being the youngest, he looks up to his elder siblings, but he treats them no different. But he WOULD protect them if need be. First to Last
