Yes, there might be some out there. Fanfiction often combines different universes in creative ways. However, it could be a rather niche combination as Harry Potter is a wizarding world and Oryx the Taken King is from a different gaming universe. You'd probably have to search on specific fanfiction websites to find any such crossovers.
Maybe it would center around a prophecy that links Harry Potter and Oryx. In this fanfiction, the wizarding world and the world of Oryx are somehow connected, and Harry has to use his knowledge of magic and his courage to stop Oryx from taking over both worlds. The story could involve Harry teaming up with some of the characters from the Oryx universe who recognize his power as a wizard.
