Coordinates for base: x: -250, z: -1001, y: 109
Base includes the Pagoda, reactor shaft, sakura tree, and the Witchery area in the small valley to the immediate west of pagoda. Recotr shaft can be accessed from outside via a dirt trapdoor on SW face of pagoda base or via a travel anchor to Reactor Shaft or MoD.
I give the Video Taker permission to look around inside my base.
I would also suggest DTR's base, as he's endgame with most things, but I'm not sure if he wants people looking around in his base.
