In that light novel, they have a sort of "system" or "divine voice". Should we have something similar? Perhaps, one of the players could control the leveling system? maybe I can? I don't know. Its just an idea. I don't want the players to be leveling their characters up all willy nilly and make themselves op. I want it to be challenging.

In most of my RPs, there've been Haven Towers, which were built to protect civilization from Voidspawn incursions. And in one RP, they acted as a sort of System that created and maintained the rules of magic. So we could definitely implement something like that. But like you said, allowing players to grind would be detrimental to the gameplay experience, so we'll have to figure out a way to limit that.
