Abstergo Industries
Employers of Dr. Vidic and Lucy, captors of Desmond, as well as the company which funds the Animus. Dr. Vidic boasts of their accomplishments in more than just medical and scientific accomplishments, but any huge progressive movement within the world.
Vidic claims that Abstergo is responsible for every scientific accomplishment for the last 1000 years. Later Desmond figures out that Abstergo is the modern embodyment of the knights templar.
Abstergo is also a latin verb, meaning "to wipe away".
Through the emails we learn that Abstergo is being investigated for something called "New Fluoride", which the tested on an isloated community, were caught, are are currently being investigated for. This is the reason behind the Dec 21/12 launch of their orbital platform; as afterwords they risk being immobilized by having their assets frozen.
