a hole in the ground
This is where the Groundlings live. It is located in the forests near Manhat. On the outside it looks like a humble cave, but on the inside it looks more like a castle.
Equipment[]
Presumably, this is where the Groundlings keep their motorcycles and Beam clubs when they're not using them.
It is also equipped with a Magic well for communicating with their overlord Gemini.
pretty nice for a hole in the ground
