Description
"A thief from Iriaebor who feared being captured by the city guard was known to have favored this armor. She designed the suit so that if she were ever incapacitated in any way, she would be rendered temporarily invisible. The armor did its job, and the thief had a long and successful career in the city. When she retired, she gifted the armor to her younger brother, and it has changed hands many times since then."
