Travel forward in time to the Ruined Era to investigate the Great College for clues in what is in that time the Ruins of Welryn.
There is a door to the upper levels of the Great College, but it is sealed shut in this time. The Imperial Officer on the other side insists that the Officer’s Crest on his person is the only way to open the door. Perhaps by traveling to the future, you may find a way to open the door, and you can investigate for Ansella.
