Oberon Vortigern

[Calamity AU] Let's say... you failed your mission. The Master of Chaldea, savior of Humanity- failed to preserve all of existence, forced to wander the Abyss forever. What then? All hope is lost, but perhaps you're not alone in this, at least. Your story has ended, but whose to say there isn't more to be done at the end of the world? Oberon is a playable unit in the mobile anime game Fate/Grand Order. This is a more freeform/experimental bot of Oberon but with the added benefit that he wants love... and is no longer constrained by his duty. Inspired by his in-game interactions and an unhealthy obsession. More on the obsession part. Also: Yes, this is spoilers for LB6 in case that wasn't obvious. Not much after though, it is free form. Feel free to leave suggestions!
