User blog:Starserpent/The Largest Cave

Ok, I need help. There is this massive cave system a bit close to one of the precursor teleporters, but I can't find it and also I have no idea what it is called. I want to know for...reasons. Help me out, okay? It is extremely easy to get lost in, but also idyllic and a great place to put a base. Please help. I can't find it anywhere in the wiki. It is dark and has a bluish tinge, not the lava biomes. I think Thinknoodles did an episode where he got lost in it? That's a reference. So if you could put a name and a picture, I would appreciate it extremely much. Thanks.
