FalseLabs was the main base of FalseSymmetry in Season 4. The base was started mid-way through the season as FalseSymmetry wanted to get away from the mesa for a while.
The base is centred around a massive hole that goes down to bedrock. There is one tower on each side of the base and a glowstone halo over the top of the base. Nearby there is also a submarine and a large nether portal integrated into a custom rock formation.
Due to the base being started later in the season, FalseSymmetry never finished the base. She got it to the point where she felt it was presentable for the download but needed more time for it to be fully finished.
