"What is this place?"
Eren found himself in a place far different from what he expected to get teleported to. He looked up and saw the night sky that was studded with glittering stars. But the sky was devoid of the moon.
Then he looked around and found out that he was teleported to a barren land above a mountain. A large and expansive platform was created. It looked like the peak was chopped off by something very sharp in one go, allowing for the creation of such an unnaturally flat platform above a mountain.
The wind felt cold. But it didn't feel like it was being influenced by the snow. Plus, it was too stable to be called a natural wind– considering the height Eren sensed he was supposed to be at.
