Atok Abidemi was a member of the Salamanders Legion during the Great Crusade and Horus Heresy. Following the Battle of Nocturne, Abidemi was among the three Salamanders to discover the reborn Vulkan at Mt. Deathfire alongside Barek Zytos and Igen Gargo. The three were named Vulkan's Draaksward, his traveling companions on his journey through the Webway to Terra. Atok Abidemi, along with Vulkan and the rest of the Draaksward, eventually reached the Imperial Palace on Terra after an arduous journey.
