This was one of Ratatoskr's underground facilities in Tengu City...
Like DEM, Ratatoskr had established quite a few secret facilities throughout Tengu City for use in case of emergencies.
After all, unlike the massive DEM, Ratatoskr as a whole only had one airship, the Fraxinus. If the Fraxinus were crippled, they might not even be able to carry out operations involving Spirits.
Of course, that was no longer much of a problem. The Fraxinus had become Wu Yan's Noble Phantasm, so even if it were damaged, it could recover quickly. However, Ratatoskr's members did not know that, so the secret facilities were still necessary...
For example, this secret facility had come in handy for detaining Ellen.
In truth, if they wanted to detain Ellen, the Fraxinus would have been the best place for it. Compared to these secret facilities, the equipment and installations aboard the Fraxinus were undoubtedly far more advanced and superior.
But Ellen was no ordinary person. She was the strongest wizard in the world, and her strength even surpassed that of most Spirits!
If someone that dangerous were kept aboard the Fraxinus, then if anything went wrong and Ellen escaped before wreaking havoc inside the airship, even the Fraxinus, despite having become a Noble Phantasm, would not be able to bear the burden of her rampage.
Thus, after defeating Ellen, Kotori had brought her back directly and transferred her to this facility for the appropriate measures and interrogation.
Ellen's injuries after fighting Kotori had been severe, even worse than Tobiichi Origami's!
Yet she seemed accustomed to such injuries. Before Kotori had captured her, she had already treated herself somewhat. After being restrained and receiving further treatment, she was basically almost healed.
