Description
As you may know, Magister Duskwither sent me back here to shut down the power sources that feed the Spire. There are three of them, each located in a different place inside.

Unfortunately, I appear to be too late, and Duskwither Spire has been overrun with strange, magical creatures. While I haven't the expertise to accomplish this task, surely a, such as yourself, could do so easily?

Progress
I can't be certain from this distance... have you already shut down the power to Duskwither Spire?

Completion
I am grateful to you for your assistance, but saddened to hear that some of my fellow apprentices have fallen to their addiction.

With the power to the Spire cut off, I think I'll stay here a while and see if things calm down long enough for me to sneak in and retrieve their remains.
