Well, if it's the Heavenly Cave, and Hazama mentions "opening" the Nemesis Horizon in Ragna's arcade Mode, my guess is that the Nemesis Horizon is a way to reach the location where the Amaterasu Unit is in the Boundary. Or, like Venom said, it's a container for it. But definitely not Take Mikazuchi. If Celica turned out to be that weird-looking creature that was inside Take-Mikazuchi, though, that would be one hell of a twist.
