User blog comment:Gearslover01/Why did we search through Altair in ACI (Spoiler for Revelations)/@comment-5266147-20120809232449

because of the DIA incident in which they lost a PoE and needed a replacement, from clays sessions of ezio they found that altair had seen a map of PoE locaations, they then located a decendent of both altair and ezio for their next subject.
