Mask of Night's Reach

The Mask of Night's Reach was a powerful artifact from Kamigawa that allowed its user to steal black-aligned powers.

A copy was given to Leshrac by Night herself, who used it to gain Phage's and Nicol Bolas' touch. The real one was taken by Bolas, who employed it to imprison Leshrac within it and close the Madaran rift.
