Islinda was dressed in a nightwear that left little to the imagination. It had spaghetti straps and through the use of lace, offered glimpses of the body beneath. It wasn't just the fireplace, her room was designed in such a way to ward off the cold. She might as well sleep naked this winter and the cold wouldn't get to her.
Yet, she did not dare to sleep naked.
Perhaps, it was the awareness that she was far away from the safety of Aldric's castle, but it would be much easier running for her life with her clothes on, than without it. Not to mention, she did not feel safe, even with the amount of security standing outside her door. What if someone snuck into her room while naked? That would be a recipe for disaster. Nor did she dare to give an identity to "who" would dare to sneak into her bed.
