Subterranean Caverns
Below the flame in the sky, below the iron of an epoch of existance, you can find it. The most beautiful world, covered in soft light. You'll also find the best restaurant this side of Tarun. Go to Verti and check out Pak's Wing Board. Ask for the Spiced Nurel. Best thing ever.
Geography
Covered in soft light from glowing crydtals and bio-luminescent plant life, these underground caverns stretch beneath the entire surface of Mizar Altuni. The caverns were created billions of cycles ago when water once formed on the planets surface. Over time, this water seeped into the ground and carved out the massive halls, pooling in new lakes deep in cool rock.
Natural Resources
One of the most precious commodities for those living on the Topworld, water is transported by the Topworld Water Line from the underground lakes to the various settlements and stations attempting to eek out a living on the surface.
