Location from He Who Fights with Monsters by Shirtaloon
A world-spanning detection network on Earth — built by the Founder to monitor proto-space emergence before the incursion made it critical infrastructure.
The Grid was created by the Founder — the mysterious individual who established the Network — using 'new magic' more potent than anything seen since. It serves as Earth's early warning system for proto-space emergence, detecting dimensional instabilities before they produce monsters or collapse into reality. After the incursion, the Grid went from a precautionary tool to essential infrastructure. Without it, proto-spaces would manifest without warning, and the already chaotic magical incursion would be catastrophically worse.
Not a physical location but a magical network of nodes spanning the entire Earth. Invisible to normal perception, it functions like a magical radar system, detecting the formation of proto-astral spaces before they fully manifest.
