Grass Pyramid

The Grass Pyramid is an ancient Deadeye structure. It predates the Precursors and even the Moths.

Description
The entrance is surrounded by floating cubes of diamond, gold, emerald, and aquamarine. On the top of the pyramid are some roses. Inside a pillar of water flows directly down from the ceiling. On the far side is a window which separates the interior from a flowing waterfall, which originates from the top of the pyramid.

Purpose
It's purpose remains unclear. Perhaps it was abandoned by those who inhabited the island and left long before Ro, Ren, and Yan founded Deadeye.
