The Obsidian Dreadnaught is a spaceship that is the main vessel that takes the Santun through dimensional gates. It features winding corridors and dwellings for each of the Sorath and other high-ranking Santun. Once the CAS/CIS and the Lightbringers learned about this massive Santun mothership, plans began to get drafted to infiltrate and bring the ship down. Zorten,Zeth, and Bellator were among the group that infiltrated the mothership, sending what little intel they could gather back to the CIS and the Lightbringers.
The conflict is reaching a momentous climax as CAS and Lightbringer forces have begun attacking the ship.
