I figured the lore given for him is decent, but my biggest complaint is how he was turned dark by 'losing a playfight' with his friend stare. So I've retconned and tweaked a few things: Eon was always unwell as a child. He was emotionally unstable, and always strived for power. Stare was his only friend as a child, as Stare was the only person who truly understood Eon's issues. But soon, they started having a falling out. Eon was getting madder day by day, until he couldn't hold it in anymore. During a playfight with his friend Stare, he had let his guard down and lost the fight. This sparked a fire inside him that would soon grow to overtake him. He stormed off without saying a word, and never spoke to Stare again. As he matured, his strive for honor and power slowly grew a hold on him. But now, he was more sophisticated, and formulated various plots to gain power. One of such, was to gather various people who all strived for power just like him, and enabled them under his new found army, called the Dark Army. The Dark Army's main goal was to defeat anything that hoped to spread light, and have all of Anora and many other worlds under their rule.
Music by me. Dialogue in a few episodes may need to be tweaked just a bit to fit with this. And in whatever episodes his humanoid appearance shows up in, it'd be recommended to try and replace those too.
