Ivanovich dying in the hands of his father, as seen in the Glyphs
Ivan Ivanovich (28 March 1554 – 19 November 1581), of the House of Rurik, was the heir apparent of the Tsardom of Russia, being the second son of Ivan the Terrible and Anastasia Romanovna, and elder brother of Feodor.
The Assassins were somehow involved in Ivan Ivanovich's death.[1] Underneath the Library of Ivan the Terrible, a portrait of Ivan Ivanovich hid a secret Assassin entrance to the library.[2]
