Zathract was stationed at the bottom of the valley near the Keep with the rest of the Irish, Australian and African forces. He and Nixion - another Australian mage - were sent with Erskine Ravel, Ghastly Bespoke and Anton Shudder to investigate Roarhaven. After infiltrating the Sanctuary, Zathract and Nixion split off from the Dead Men members, taking half their Cleaver forces with them, to secure the area. When Ghastly next checked on them, Nixion reported that they had half a dozen sorcerers in shackles. They were told to stay where they were and await further instruction. The second time Ghastly tried to contact them, the Black Cleaver had decapitated both Zathract and Nixion and landed their heads at Ghastly's feet.
Zathract is based on an Australian fan of the books.
