The following account was recorded in the agent's log during your transmission: Cascading crystalline formations fill a vast, underground chamber, refracting the faint, pale light of luminescent mushrooms that grow like a constellation across the vaulted ceiling. The air is thick with the scent of damp earth, and the sound of trickling water echoes off the stone walls as it flows into a massive, mirror-still pool that perfectly reflects the eerie light. A flawless, Sumerian-style temple rises from the pool's center, its entrance guarded by a pair of imposing, obsidian statues that seem to be absorbing the surrounding light. The temple's peak pierces the solid rock above.
