Ganthrifal was a nathrezim dreadlord who had been skulking about Silverpine ever since the Forsaken undead had taken the Undercity from the Scourge. The misguided Forsaken warlock Blarus Whitrick's magical experiments in the ruined castle of Gaval Moch drew the dreadlord's attention, and he spied on Blarus for some time before concluding that the foolish and naïve warlock could be a useful tool for the Burning Legion. "He has a fondness for expensive spirits (finding the pun extremely amusing) and likes to remember Draenor's golden age."
