Isaiah
- "I am no longer a Templar! I am become death, the destroyer of worlds."
- ―Isaiah[src]

Isaiah (died 2016) was a member of the Templar Order, serving as the director of the Aerie, an Abstergo Industries complex.
He was also a former member of the Instruments of the First Will, but he left Juno's followers to pursue his own plans for global domination.
Biography
In 2016, after the Templars captured a team of teenagers using a stolen Animus to find the Trident of Eden under the guidance of Monroe, Isaiah, and Victoria Bibeau tried to discover what they knew.
In order to do so, the two Templars decided to use honesty, Isaiah confirming that they were both members of the Templar Order and that Abstergo was indeed a front for the secret society but insisted on the benevolence of their organization. They successfully convinced some members of the group, who then revealed to the Templars the location of a dagger which, in actuality, was one of the prongs of the Trident owned by Ulysses S. Grant until his death.
