Freezing Prisoner

Growing up the last years of his live in poverty on mars, the once called Yuri never expected anything good to happen in his life.
However, even he did not anticipate being chosen by the Spartakan AI, becoming one of the Kosmanavts - an elite group of Space Soldiers that were practically demigods for the averadge human. Transported into a alien magical world, he found himself facing against terrible aliens, traitors, monsters, other Kosmonavts - and much worse - in a deadly battle of survival.
What's worse, the new powers he managed to aquire just so happened to make his already cold life even worse.
