There was some dispute as to whether the voadkyn race was created when Othea, wife of the giant deity Annam All-Father, had an affair with Ulutiu, or whether the race was the product of Annam. A giant stormazîn apparently once proved that Dunmore was Ulutiu's child and that Othea tricked Annam into believing that he was his own so that Dunmore could spy on Annam and his children, meaning that the voadkyn were giant-kin and not "true giants", but the voadkyn preferred to believe the opposite.
Like all the giant-kin races, they were never granted a portion land by Annam from which to found their own "dynasty" inside the kingdom of Ostoria. They were initially welcomed by their fellow giants and learned their ways, but once their true parentage had been discovered by Annam he cast them out. They became excluded from the societies of true giants, despite Othea's best efforts to protect them. They then decided that since Annam had not given the forests of Ostoria to any of his sons, they would take them as their own domain, after which they cut off most relations with both giants and giant-kin.
Voadkyn were known to be highly susceptible to all forms of lycanthropy and were one of only two giant races in which "true" lycanthropes were known to exist. These true lycanthopes were a form of werebat that the voadkyn referred to as shadkyn and a great enmity existed between them and their non-afflicted brethren.
