Seal of Time

Find the source of madness.

The good news is that the source is not far from here. The bad news is that it's completely cut off from the main structure. The whole room is isolated from the Citadel, so to say. So it's near, and at the same time, it's very difficult to access. The architectural paradox easily achieved by adepts of dimensional magic. I wonder for how long it's been here...
However, we can use the teleportation network of the Citadel to enter. In fact, it's the bad news. You will have only a few moments to evaluate the situation and defend yourself if necessary.
Stay alert.

Let's go. It's time to put an end to it.

I don't feel so good. What is this construction?
It looks like a device.
