The Drexelhand family was one of the leading families on Korthos before the war. The Heyton's were another family and in an effort to cash in on the war effort, they negotiated with House Cannith to build forges to create the fighting machines known as the warforged. Their plan did result in enriching them but because of the mystical forges, the war came to Korthos and caused much damage to all. The Drexelhand holdings were largely destroyed, while Heyton's used their connections to profit and rebuild.
Generations later, 2 brothers worked for the Heyton's. Jacoby managed some of the properties while his older brother Grondley was in 'accounts receivables'. Using his knack of magic combined with some study, he was able to either charm or scare the late accounts to get current, or else. Drenyl Fallow came to the island preceding the Sahuagin invasion to establish a foothold and recruit disgruntled villagers to join the "Cult of the Devourer". He turned Jac's resentment toward Heytons for having to work places that his family had once owned, into hatred and the desire for revenge. Grondley fought the Sahuagin and only learned of his brothers traitorous deeds while defending the Wavecrest. Jac was killed but Grondley was again forced to fight his now dead brother when Drusen was abducted. Overcome by remorse and under suspicion by the rest of Korthos, Grondley had to flee.
He is now turning his mystical knowledge to the hope he will be able to restore true life to his brother, who at least for the time being, is summoned to assist Grondley in his adventures. Recently as part test and part revenge, Grondley secretly returned to Korthos and ressurected Drenyl in the form of a rat to serve him as a familiar.
