A mixed-species team of special-operations soldiers have volunteered to covertly delivery Leviathan artifacts behind enemy lines. These attacks aim to make Reaper creatures thralls of the Leviathans. On a small scale, this could cause chaos and disruption. One a large scale--and if given enough time--it could form an army of Reaper creatures dedicated to exterminating their own kind. The team's major limiting factors are the small number of artifacts and the reluctance of Alliance commanders to operate openly with such a potent weapon for fear the Reapers might develop and countermeasure.
