I'm not sure how well Liv would get along with Abdiron though I'm not opposed to them meeting. She really doesn't trust beings that are superior to her mostly because as a complete egomaniac she's terrified of the idea of not being the most In Control in the room.

That said she has met two supremely powerful beings and while she didn't get along with one, the other she got along pretty well with but that MIGHT be because he hid his true nature from her and acted like a mortal with similar interests.

I'd be down for them meeting and seeing if they work out organically if you are. She might also drive a proper hellgod up a wall given how absolutely irreverent and self important she is, which I'm a bit worried about, because she absolutely couldn't stop one of them from smiting the heck out of her.
