Astrum Aevitas

Astrum Aevitas, known far more commonly as The Sun King, is the leader of the infamous Rogue Guild, Heartstring. Born into a life of abuse and poverty like so many others, Astrum would find that his Mutant heritage made him a target for abuse and discrimination. As such, Astrum was hardened into a capable warrior, aiming to change the seemingly pre-determined fate for him and his kind. Upon the death of his older sister, Astrum would join the mutant-led organization, Heartstring. Quickly rising through the ranks, Astrum would push a more violent campaign. His consistent success led him to be nicknamed "The Savior of Mutants," and was regarded as a messiah by many within the organization. Upon the brutal assassination of the prior leader of Heartstring, Astrum would take up the position as it's head, ensuring that he would not rest until Mutants were given the respect and rights that they had been denied for so long.

Backstory
Born in one of the many Mutant tribes across the Wasteland, Astrum Aevitas was the product of a night of passion between two mutants who had relatively little to do with one another beforehand. When he was still but an infant, Astrum was separated from his parents in a small skirmish between the Axis and Traditionalists. Alongside his elder sister, Astrum was the only one of two individuals to make it out alive and unscathed. From that point on, facing extreme discrimination no matter where they went, Astrum's sister Solaris found the town of Nammerth. Despite the still rich atmosphere of discrimination, Solaris and Astrum had found a place where they could properly live, (mostly) without fear of being killed.
