Meeliw'ai
Functionally, this world would be described as another campaign setting in the Dungeons and Dragons multiverse (Greyhawk, Dragonlance, Forgotten Realms, and Eberron being some of the more well-known). There are many rules used that are similar or borrowed from the D&D tabletop RPG and narrative books. However, In creating this universe, somethings are tweaked or changed. The best way to describe this would be to think of yourself in a carnival funhouse of mirrors. You know what you look like in a normal mirror, but the reflections you see in the funhouse are warped or twisted, or sometimes just wonky. In the world of Meeliw'ai, sometimes things will just work a little differently.
An example (which doesn't give anything away, so no spoilers) might include the use of steam punk-like technology where magic cast by wizards and prayers sang by clerics to their deities also exist.
Understand that this is a dynamic world, and if you step away, things may have changed by the time you check back in.
