===Post-Heresy===

After the enthronment of the Emperor Vulkan personally led a vicious counterattack from the Palace Throneroom all the way into the outer districts of the the Imperial Palace, striking down all traitors he came across and relishing in their annihilation. He then encountered [[Ultramarines]] [[Chief Librarian]] [[Titus Prayto]], who had been dispatched by the newly arrived [[Roboute Guilliman]] to gather him for the coming [[Grand Council of Reconstruction]]. Caught up in the desire for vengeance against the Traitors, he initially refuses Prayto requests before relenting.{{Fn|26a}} In the subsequent Grand Council, Vulkan spiritually supports Dorn, [[Leman Russ (Primarch)|Russ]], and [[The Lion]] in launching a Punitive Crusade against the fleeing Traitors rather than adopting Guilliman's more cautious strategy of consolidation. However in the end he issues his support based on rationality over satisfaction, and comes to reluctantly support Guilliman.{{Fn|26b}} To support Guilliman, he deployed [[Atok Abidemi]] alongside a newly arrived force of Salamanders to help in the [[Retaking of Luna]].{{Fn|26c}}
