The spatial magic of that spell was crude and unrefined, and it made him reach the destination with a strong feeling of vertigo. The walls of the ruin were of the same style as those on the surface; the only apparent difference was that some blocks and walls were cracked, or had simply collapsed...
Ikky wasn't an expert, but those ruins must have been several thousand years old. The air was barely breathable; mold, dust, and a low oxygen density made it difficult to exhale, which was necessary to maintain a 100% body, even though his body had improved and was much more efficient than before.
There wasn't a shred of light in the tunnel; luckily, his blurred vision had now advanced to complete black vision, although it was still unsettling. Ikky knew Lei could see in the dark like he could, but for Lei's skills as a shadow runner, total darkness was a handicap.
