The Sinister Six
Father Llymic is one of the Elder Evils, a being of cold and darkness hailing from The Far Realms. Apparently summoned to Sor’drim in aeons past by elven wizards, Father Llymic appears as a kindly old man, but this is almost certainly not his true form. Thriving off darkness, Father Llymic is harmed and subdued by light, but when exposed to it his body radiates intense cold. Served by legions of Broodspawn, an infected, twisted form of life, Llymic is heavily resistant to most magics and weapons, and is capable of being harmed only by Calabrand. Supposedly, Father Llymic is entombed upon the peak of a great mountain.
