John Standish

John (unknown – 2013) was an IT technician working for Abstergo Entertainment, a subsidiary of Abstergo Industries.

He secretly worked in association with Shaun Hastings and Rebecca Crane, in order to gain access to Abstergo Entertainment, and its servers, using an analyst working on the Sample 17 Project to do so.

After manipulating and attempting to kill the analyst with a lethal injection, John was shot and killed by Abstergo Industries' security guards. Before he died, he mimicked Bartholomew Roberts' accent and shared the pirate's look, revealing himself to also be a Sage - a reincarnation of Aita, one of the members of the First Civilization and husband of Juno.
