Hell
This home will take some digging to find - definitely a modern look!
Starlit Heavens
The main base with a view of the stars. Includes teleports, several viable NPC homes, and crafting/storage.
Corruption
I think the original owner of this home was probably the unfriendly sort. Your NPCs won't appreciate this home, but you might find it useful!
Dungeon
Room for four NPCs and display space for your armors.
Beach
Fish to your heart's content at this end-of-the-world resort.
Tree
Treehouse including two viable NPC homes (top and base).
