Already rolled to see if the ring survived in the first post of the other thread – the die roll was an 8.
Looking at the planner, Vibria doesn't have anything that requires a lab for a while, so she can just move into the empty tower on the top right (northwest?) corner of the keep, near Carmen and Kesara. Once the structure is rebuilt she'll move in and refurbish her lab. For now, she'll forego having a lab until the new tower gets rebuilt. She'll just be cold. (As always.)
Lucia, for her part, is shaken that Vibria would be so careless and reckless as to destroy their home and will try to find alternate lodgings for a while. Perhaps she and Epona can find something. Or, if not, wherever the other covenfolk dwell. (But if the two can get their own apartment, they would.)
