Art inspired by the announcement of the title of the seventh and final Harry Potter book, Harry Potter and the Deathly Hallows. Going on the theory that the deathly hallows correlate to Arthurian legend and Celtic legend, representing four objects of sacred meaning, making them the items of the Four Founders. The Crystal Ball is meant to be Rowena Ravenclaw's relic, and the wand Godric Gryffindor's. I'm proposing that Salazar Slytherin had a brother sword to the one Gryffindor had that's now in the Headmaster's office, which is why there's a green tinge to the blade.
