Huh? I think your misquoting me, slightly - or maybe I explained it poorly- ASol knows Nagakabouros -- meaning he understands and is aware of that god. As powerful as ASol is, he's not on that level. --They don't hang.
In a story, Nagakabouros is a philosophy and an important religious belief. So hopefully it/her will show up indirectly in many of the upcoming stories-- esp those surrounding Bilgewater.
Personally, I'd love to do comics or novellas about Bilgewater. I love Illaoi, Gangplank, TF, Graves, and Lil' Okao holds a special place in my heart.
(And of course, I'd live to follow up on Jhin mission in Piltover.)
