This is the Underwater Research Lab I built, and I am showing to satisfy our good friend @CausticKrana
The design of the front was meant to vaguely look Hau-Ish, but not too evident.
Here you can read the signs. They may be temporary, I dunno.
Inside is a most familiar looking pool, no? It is meant to evoke the pool from the one hut in MNOG. But unlike that one, this one has a purpose.
Going down into the pool will lead you to a hatch. And because Minecraft physics, so long as said hatch is only opened, and not broken, water will not flow into the area below it. That's right, the pool is a decoy to sway any curious individuals in-universe away from the secret lab.
Going down the hatch will lead to a dry room with two doors. I hope to add more soon.
For now both of thse doors lead to basically identical hallways, and rooms beyond.
These identical rooms(identical to eachother, not identical to the previous room) are both made of Sea Lanterns entirely, only on the inside. On the outside, they appear perfectly normal. The Metal door leads to the ocean outside.
I hope to have two more doors in the hatch room that lead into hallways that lead into larger and expansive lab complexes, that maybe go deeper down into the sea.
