Graia

Graia is a Forge World in the Segmentum Tempestus of the Milky Way Galaxy. The planet is home to Legio Astraman, a Loyalist Titan Legion of Adeptus Mechanicus.

History
Graia became a site of battle between Imperium, Orks and Chaos. The world was invaded by the million-Greenskin strong WAAAGH! Grimskull, targeting planet's precious Titans and other military technologies. The 203rd Cadian Shock Troopers Regiment of the Imperial Guard was the nearest Imperial forces which joined in the defense of the world. The Ultramarines 2nd Company under the command of Captain Titus was also deployed to Graia to slow down the Orks advance until an Imperial liberation fleet could arrive and secure the planet. The Forces of Chaos launched their own invasion of the Forge World. The Imperium of Man was victorious over its enemies. These events occurred in an alternate timeline where Titus was the commander of the Ultramarines 2nd Company rather than Cato Sicarius.
