"Hell" and "Heaven" for a DnD setting involving League of Legends?

So, in the Dungeon Master's Guide, it talks about how you need a plane for fiends, celestials, and elementals. Does the world of Runeterra have any sort of "hell"? I've already got one place for fiends that fall under the category of demons with the Void, but I'm trying to see if there is a hell place. In my world, characters like Eve and Tahm Kench would be the "devils" of this world, and they would originate from this place. So, is there already a canon place for this? Or do I need to make up my own?

This probably isn't that canon anymore, but I remember Kayle had something similar to a heavenly place from which she originated, so I'm likely to use that. But if there's a more canon place, then I'll use that.
