The following account was recorded in the agent's log during your transmission: Shards of bright sunlight pierce through stained glass panels set into the curved ceiling of a Byzantine-style, subterranean baptistery. Umm, wisps of frankincense smoke rise from censers suspended above a perfectly still, rectangular pool of what looks like pure gallium - it's just... reflecting the intricate mosaics covering the vaults above, somehow casting a reverse, reflected image of the pool itself onto a large, glassy obsidian slab embedded in the baptistery's wall. The air's thick with the scent of wet stone, and there's a faint electric charge here, like it's tied to the pulsating beat of a... distant drum.
