Teleportation and portals... very interesting. Passing through another place. A tunnel. Main exits and entrances from the Demonic Subspace are... watched. Through immense cost, can open a portal to the Human World. Risky. Expensive. Need anchor.
But what about "tricking" it open? Reality thinking both places are the same, bridge forming "naturally". Using ambient Magica to keep it open, no cost to self.
No way to watch everywhere, can make many, maybe even on an individual demonic level.
Right now possible with Imps. Amazing. Genius! We are so great.
But imps are worthless. Need more researchers....
