As a little nod to the Underdark from D&D and Baldur’s Gate 3? Since the tree sits right next to the pond, imagine exploring a maze of tangled roots that eventually opens into enormous caverns filled with glowing fungi, crystal formations, underground lakes, and hidden passages connecting to the pond. There could be unique creatures like cave crickets, translucent springtails, crystal-armored beetles, and spiders lurking among the roots. Maybe even a massive underground boss guarding the deepest chambers. It could introduce new resources, crafting materials, and opportunities for underground base-building. I think it would be an awesome way to expand the map while adding a mysterious, slightly eerie atmosphere to the game. Plus, “The Under Bark” just feels like a perfect Grounded-style reference!
