Velkayor

Velkayor is an Imperial prison world, and is uniquely designated as an Adeptus Astartes homeworld of the Blades of Redemption Space Marine Chapter, a Successor Chapter of Ultramarines lineage, that believe in the unique philosphy of self-guilt of people who committed crimes against the Emperor. The chapter continuously seeks an unreachable redemption in the eyes of the Emperor.

Background
The homeworld of the Blades of Redemption is Velkayor, a prison planet. Velkayor is a monster of a prison where the criminals of over thirty worlds are sent, because of the population being swelled up of the Imperium's unwanted filth the chapter recruits the prisoners of this world and puts them through hellish conditions for their recruitment. The World of Velkayor is a bleak world as constant overpopulation forces the Arbites to do frequent purges on the prison population and sometimes let the prisoners kill each other to free up space, even if prisoners hate living in the prison they can't go anywhere else as the planet as the landscape is covered in harsh deserts. The temperature will kill you before the hostile wildlife does. Occasionally, around a certain time of the year, the prisons go on hunts for beasts or other prisoners, each kill elevates the prison's standing of the killer allowing more privileges in their lifetime sentence.

Chapter Recruitment
Unlike most chapters that recruit from Death Worlds the Blades of Redemption focuses on redeeming the dregs of the Imperium. The chapter takes vast numbers of prisoners most of the time by force, those that are taken are then immediately taken to a large arena where the thousands of aspirants have to fight in a large scale battle and after those that survive the allocated time limit must then fight in one on one duels to the death. After the battles the aspirants are then spiritually tested, those that seem against the god emperor or too rebellious are cut from the stock, those that are still considered worthy are then taken to train on the chapter's training ground called The Cage on Velkayor where the aspirants are broken body and soul making the recruits feel guilty for their crimes and the only way to be redeemed is to die on the battlefield against the enemies of man. By the end of the trainees recruitment a rebellious child will be turned into a fanatically warrior of the god emperor.
