I had ventured back home to Summerset Isle last night to position a teleportation field in Cloudrest. The town and much of the landscape had changed shape. It appears our placement and agenda overlapped a critical moment in the turning of an age. High council had deemed it necessary to relocate the tower using experimental magic.
The magic was successful, but they did not anticipate a full on war with the Daedra at that very moment. From what I gather, the tower appeared to be destroyed. Pity, I would have liked to witness the terror for myself. Perhaps there will be other sights or carnage that time has yet to reveal.
