Cursed Cape
The first thing Arthur paid attention to was the thickness of the dark cape. It was very thin and felt just a bit thicker than paper which was strange as looking at it one would find it hard to tell.
"The color of the cape makes it hard to tell that… though why would a cape be this thin? They're supposed to be thick aren't they?" Arthur wondered.
Then next thing he picked up on was the texture of the cape. It was very smooth, as if made out of fine silk and yet he could tell it wasn't silk either.
'Definitely some kind of magical fabric… and surely has enchantment on it.' He thought.
One other thing was the color of the dark cape. Arthur realized the inner side of the cape was actually a bit more dark than the outer side. It was hard to describe though as one could only tell that at a close look.
