Well spoken ogre.
Kurgosh is actually the rank, not name, of this character. Kur Gosh means the Herald of Gosh. Gosh being a powerful Oni type demon. If one Kur is killed another will likely take it’s place shortly after, as all Kurs are linked to the Oni who act as Gosh’s luitenants and generals. By allowing his “superior officer” to possess him, Kur Gosh was able to channel freezing energy moments before he died.
Some time weeks after the original Kur Gosh was defeated by the party, a second Ogre calling himself Kur Gosh was again witnessed following the party.
