Try it of course.

Really not wanting to just walk out naked, you try wrapping the large blanket around you, and your hand starts to glow, so you quickly rip the blanket off before it vanishes as well.

After a few minutes of trying to cover up, the best you find you can do without your mark threatening to destroy the last piece of coverage available... is just holding it across to cover either your front or backside...Shit.

Peeking through the front window, it at least seems that some of the crowd has dispersed, though no doubt news of you exiting the house naked has spread throughout the people already.

While searching for coverage, you did find a letter that had fallen to the floor, its from Seeker Pentaghast, the woman who imprisoned you and pretty much got you into this mess in the end... great, she wants to see you in the chantry, wherever that is.
