Horus himself would be a central character. He would bring his own set of powers and a whole different mythology into the story. Dumbledore could also play a significant role. He's wise and powerful, and he might have some knowledge about Horus or the connection between the two worlds. Maybe he's been waiting for Horus to arrive for some greater purpose. And then there could be some minor characters like Neville Longbottom who could end up being unexpectedly helpful in the journey.
In addition to the regular Harry Potter characters, we could have some Egyptian deities or spirits related to Horus appear in the fanfic. They could be trying to reach out to Horus or be part of the reason he can't return home. And from the Harry Potter side, characters like Sirius Black (if he's still alive in the fanfic's timeline) could be involved. He has his own brand of magic and could be a great asset in protecting Horus and helping him on his journey home.
