2 Bases. One is a Cyberpunk city (Admin note: only one base per planet per player is uploadable. Cyberpunk city is visible, the other is not.)
Notes
Cyberpunk city is on ocean side of Planet, Living Glass farm is on the Continental side (Admin Note: Only the base that is uploaded to the servers will be visible to other players.)
My starting planet, which was perfect so no need to explore anywhere. It has two bases. The first base, "Further", is nominally based on the Magicians series. The second base is based on the Myst island from the eponymous game (pun intended).
