The Abstergo Foundation Rehabilitation Center, commonly referred to as simply Abstergo Foundation, is a subsidiary company of Abstergo Industries based in Madrid, Spain which, like its parent company, operates as a front for the Templar Order. Ostensibly the Foundation's goal was to find a genetic "cure to violence" by locating an Apple of Eden.
Headed up by Dr. Sophia Rikkin, the Foundation held imprisoned a number of subjects who they would force into the Animus in order to explore their genetic memories—many of whom were either descended from or active members of the Assassin Order.
On 22 October 2016, Callum Lynch, a descendant of the 15th century Spanish Assassin Aguilar de Nerha, was brought to the facility by Sophia Rikkin and placed in their Animus. After several sessions in the Animus, the Templars succeeded in locating Aguilar's Apple of Eden, but were forced to flee the facility when its inmates organized a revolt and overcame the guards.
