What it doesn't explain - why cheat codes are in latinised English.

It seems possible to me that MoR spells work a bit like the URLs for TvTropes pages. When a new spell is created, it is attached to an arbitrary incantation of the casters choosing. From then on, that incantation recalls that same set of effects no matter who performs it, like entering a URL into TvTropes to retrieve a page that someone else wrote, when just yesterday that URL led to a blank page.

What I want to know is whether Atlantis was the origin of the system or merely the last society to have edit privileges. (Maybe they abused the system and destroyed themselves so whatever's running the simulation brought the banhammer down on the inhabitants of the MoR verse, and thus began the decline of magic?)
