Brother Tobias was a member of Sergeant Remas's squad, in the Scythes of the Emperor Space Marine Chapter shortly before the fall of Sotha.
The squad tried to apprehend the first Hive Ship which approached Sotha, prior to the planet's destruction by Hive Fleet Kraken.
After inserting by Boarding Torpedo, they ventured into the ship but were attacked by Tyranid creatures. While most of the squad was killed, eventually only Sergeant Remas and Brother Tobias escaped after crippling the ship.
Remas and Tobias drifted on their own ship until it was recovered by the Ultramarines. By that time, Sotha had fallen to the xenos invasion and was already a dead world.
