- This article is about the Isu device. You may be looking for Abstergo Industries' satellite, Eye-Abstergo.
The Eye was a device constructed by Minerva to manipulate the underlying calculations of existence, with the ultimate aim of preventing the 2012 coronal mass ejection. However, when she learned that Juno had been tampering with the Eye for her own ends, Minerva was forced to destroy it.
During her imprisonment in the Grand Temple, Juno repaired the device to store her consciousness, and manipulated Desmond Miles, a human with a sufficient amount of Isu DNA, into using it so that she would be released. In the meantime, Minerva constructed a second Eye to commune with Desmond through the memories of his ancestor Ezio Auditore da Firenze, and used it for a final time to see if he would find a way to prevent the catastrophe on 21 December 2012.
Seeing that Juno had survived and manipulated Desmond into using the Eye, Minerva warned him not to activate the device, believing it would be better if the world endured another apocalypse than allow Juno to be freed. Desmond disagreed, stating that Minerva's solution would offer no hope to the world and that humanity would find a way to resist Juno's efforts, before activating the Eye and saving the world, at the cost of his own life and unleashing Juno in the process.
Only hours later, Abstergo agents recovered Desmond's body from the room. However, the Eye had disappeared from its pedestal.
