Tartarus was born unto a world that was unforgiving, cold, and desolate. Tartarus wasn’t an overfed pet robot that refused to hunt metaphorical mice or a spoilt princeling that inherited a gigaton of generational wealth and sat idle complaining about how unfair life is.
No, he was an immaculate clone of what humanity had called Ambition, and so he desperately wanted to tame the Universe and make a name for himself.
In his hubris however, Tartarus lost himself to the very ambition he was created from. Without a single anchor of reinforcement from his peers, the once immaculate primordial being, lost himself to a desolate land far beyond the reaches of the divine Elysian fields.
