Pentakill's Lightbringer, Who is Gloria?

So in the song you have all probably heard and love, I noticed the lyrics do not say "glory" they say "Gloria" I may have simply not read a piece of lore since I am mostly interested in mid laners. But my only theory after one very lazy Google search is that the song has something to do with Leona, and I am fairly sure that is not just a stage name, eheh.
