Suit of Sorrows

Origin
The Suit of Sorrows was created in 1190 during the Crusades, and given to a Knight, Sir Geoffrey De Cantonna who was supposedly pure of heart. The suit drove him insane, and he slaughtered several hundred people in a remote Alpine valley. To protect the knight’s reputation, there was a cover-up that claimed that the Moors were responsible. The Suit was retrieved by the Order of Purity, a splinter sect of the Order of St. Dumas. It is said that the suit is able to impart strength and speed to those who wear it, but it will destroy anyone who is not pure. Years later, the armor was bestowed upon Batman by Talia al Ghul as a gift, and although it made him significantly stronger and faster, he was forced to stop using it when he began to believe it was somehow corrupting him and making him more violent. However, Batman was unable to bring himself to destroy the artifact, and instead chose to store it on display in the Batcave. After Batman's disappearance from Gotham City during Batman R.I.P., the suit was stolen from the Batcave. Since then, Azrael has begun using it.
