So, I was wondering around my YogBox world, when I came across this. It originally was surrounded by a small sandstone pyramid, which I destroyed and sold to my Millenaire village. Anyway, there's a big staircase that goes down to an obsidian maze, that is 3x1 blocks tall/wide. It is MASSIVE. There are many chests throughout it containing things such as arrows, redstone, or other things found in dungeon chests. I couldn't finish exploring it because I had run out of torches. Does anybody know what this is, or what mod it is from? Sorry if the screenshots are oversized.
(BTW, the tower in the back is a Battle Tower, a mod that is included in the YogBox.)
theres a boss at the end which you have to destroy by knocking the fireballs it shoots at you back at him (think zelda ocarina of time final boss fight with gannon), afterwards, lava will slowly fill the room afterwards, and a staircase will open behind you leading to the surface and a chest filled with good loot.
youll know when your close when you hear it under you in the maze, and when you find a trap door on the floor it drops into the main boss chamber where all i said above takes place
