An offshot of Haven, this underwater base was first created as a contest site.
Haven can be accessed from the StTheo line off the Sanctum nether rail or the Haven line off the Transcontinental overworld rail. One can also use the TARDIS network to reach Sanctum, then use the overworld or nether rails from there. Directions are provided once you exit the portal or TARDIS.
StTheo
- Hull must be made of sensible blocks: solid, non porous, non-organic.
- I'll try to be lenient about this: cobblestone would be ok, wood and sponges would not.
- You can have non-hull blocks on the inside or outside of the hull.
- Glass is acceptable for the hull (and might look nice).
- Doors between modules are recommended, iron or piston doors are required for module pressurization.
- Modules with direct access to the ocean must be pressurized.
- Piston doors are acceptable and look cooler. They also take up more space, and traditional redstone doesn't really handle well underwater.
