While arrangements had been made to ensure that they were comfortable, the room that Ashlynn and Nyrielle retired to after the banquet clearly spent much of the year as a storeroom in the back of the fortress.
Carved from the rock of the mountain itself, the room met all of Nyrielle's requirements. There was only one door in, there were no windows that could let sunlight in, and a heavy bar could be thrown across the door from the inside to ensure she was undisturbed during daylight hours.
As a place to store a chest of clothing and her daybed for a few days' visit, it was more than adequate on those points alone. As a place for Ashlynn to stay, however, their hosts had taken additional steps to make the room comfortable.
