They were out of realspace? Tiberius did not know what to make of this. He supposed it meant his duty as a mortal servant of the Emperor was coming to and end. Being lost in the warp meant they would soon be devoured by daemons. However, he would fight gloriously and die with their bodies at his feet. He took a breath, breathing in the sacred air of the Astartes vessel, and then opened his eyes, placing his fist upon his chest. 

"My duty is my fate. My service, eternal." 

Once dismissed, Tiberius would give the customary Black Templar salute and march off to his living quarters, donning his power sword and blessed bolter, hoping he could honor their previous owners by spilling the blood of mutants and traitors this day. Along the way back, he stopped at the barracks of the Cruiser, calling the Initiates to gear up and reciting the litany of the Black Templars. As they gathered themselves, he raised his fist in the air. 

"No pity, no remorse, no fear!" He incanted. 

"No pity, no remorse, no fear!" The roared back. In the time it would take an Imperial Guardsmen to sneeze, the Astartes of the fabled Black Templar's chapter were arrayed in full combat gear and within formation, vigilant and as still as the baroque statued designs that covered their Cruiser, and their legendary Fortress Monastery.  

In an ordered fashion, he let them through the grim corridors of the Battle Cruiser to their designated Assault Rams, filling the fore of the contraptions to the brim. As the Cruiser struggled during the ensuring fire fight, Tiberius could only pray the machine-spirit would hold on but a bit longer. 

"You carry the Emperor's will as your torch, with it destroy the shadows!" Tiberius called before all was fire and blood.
