-Tyranny-
The Avengers have just defeated Loki, however, for some reason the Tesseract is acting weird. A bright, blue light blinds everyone and as it subsides, there stands a beautiful woman with deep blue hair and crimson eyes. Holding the Tesseract, she looks at it with wonder. This woman is Raphael Tempest, the Lord of Wisdom, the Knowledge King.
Loyal subordinate of Supreme Deity Rimuru Tempest, she has been sent here for an unknown purpose. With unimaginable power, she defies logic, she overrides concepts and she wields knowledge like a weapon. The Infinity Stones are a useful tool but a tool nonetheless, Raphael deems them a helpful accessory for her lord and so she deems them under her ownership.
(Now I'm just warning everyone. My previous version of this story I kind of held back on how overpowered Raphael could be. Not this time. This is pretty much wish fulfillment, no one in the MCU can stand up to Raphael and I'll make it so).
