The inverted pyramid

The spatial magic of that spell was rough and unrefined, and it made me arrive at the destination point with a strong feeling of dizziness. 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 directly collapsed...

I was not an expert, but these ruins must have been from several thousand years ago. The air was barely breathable; mold, dust and a low density of oxygen made it difficult to exhale, which was necessary to have the body at 100 percent, even if my body had improved and was much more efficient than before.

There wasn't a shred of light in the tunnel; luckily, my dim vision had already advanced to vision in complete darkness, although it was still disturbing. I knew that Lei could see in the dark like me, but for Lei's abilities as a shadow runner, complete darkness was a handicap.
