Advancing despite their doubts, the scientists trekked through winding pink cliffs until they stumbled upon a massive structure, unlike anything they had ever seen. It towered over them, its metallic surface emitting a soft, pulsating glow. An eerie feeling settled in the pit of their stomachs, but their curiosity overpowered their fear. They approached the structure, and as they stepped inside, they felt a strange energy emanating from the walls. The passage led them deep underground, and they felt as though they were descending into the very heart of the planet. Strange whispers echoed through the tunnels, and soon their senses were assaulted by sights and sounds they couldn't quite comprehend. This was the abrupt end of the last human expedition into Aurora Maris.
