Piri Reis

Haci Ahmed Muhiddin Piri (c. 1467 – 1553), more commonly known as Piri Reis for his legendary stature in the Ottoman Navy, was a famed admiral and cartographer.

Unknown to most, Piri was also a member of the Assassin Order, and a Master Assassin of the Ottoman Assassin Brotherhood. Though not involving himself in missions of violence, Piri served the Assassins as a technician, primarily providing them with materials and methods for crafting bombs.

He was a trusted friend of the Ottoman Assassin leader Yusuf Tazim, and also later befriended Ezio Auditore da Firenze, the Mentor of the Italian Assassins.
