Dragon of System; that was what it had become after hatching in a place that resembled the System World. Even though what Compass Carburettor had created didn't even come close to the actual System World, it did its magic as a cheap knockoff.
After all, everything was created using Mental Energy, the prime energy means that Systems relied upon and what was present everywhere in the System World.
After it was born, it was able to restrict a System to a certain extent. But, the Dragon of System was only able to unleash one attack before it became weak. It had just hatched, after all. And in this world, the energy it required to cultivate wasn't available.
And as it had also absorbed the laws of the Apocalypse World, it was birthed as a one-horned Dragon of System.
