I do like the self-awareness, and the hard-coded railroads of the world existing alongside the game.
Kind calls into question whether all the people existing within that setting are "real" independent of the game, or if that entire universe is the "game", and they all are real as it pertains to the needs of the setting and the story.
But maybe that's not important, because they exist to them.
That said - I'm impressed by the fact that she was able to "literally define" Lunaria's 'cheat level mage' as grounds to write over the setting itself and change reality to fit her needs. It doesn't even feel "cheap", because this is a "game world" that's already been shown to operate on some behind-the-screen rulesystem, and if something 'exists' within the lore, then it exists in the literal sense in that world.
If Lunaria's a cheat level mage, then that means she's canonically able to cheat, and there's no boundaries to what that word can mean when applied to reality.
Truly a power befitting a dreadnought villainess.
