The Gartuli System is an Imperial star system located in the Yasan Sector of the Ultima Segmentum near the Warp rift known as the Maelstrom. The system is currently under the control of the forces of Chaos led by the Red Corsairs warband of Heretic Astartes.
The bulk of the White Scars Chapter, which called the sector home, was deployed to other conflicts across the galaxy. The Chaos forces succeeded in occupying several systems within the sector and nearly overwhelming the White Scars garrison left on Chogoris itself.
While the White Scars were able to rally their forces and successfully threw back the Red Corsairs' assault on their fortress-monastery of Quan Zhou, only the ebbing of the Noctis Aeterna and the subsequent loss of their daemonic allies as a result convinced the Red Corsairs to withdraw from Chogoris and pursue the destruction of the White Scars at a later date.
The Heretics are currently using these footholds in the Yasan Sector to continue to launch new attacks upon the White Scars' homeworld.
The Gartuli System's worlds in order of their distance from the system's star include:
- Vossos (Factory World) - The Factory World of Vossos came under siege by the Red Corsairs but still remains contested with Loyalist forces.
- Gartuli (Fortress World) - The Fortress World of Gartuli has been conquered by the Red Corsairs and their allied forces of Chaos. Gartuli is the primary world of the system and the planet for which it is named.
