Agaron

Agaron was an inhabited planet whose government was close allies with the Vulcans in the early 22nd century.

In the early 2120s when the ruling government wanted to forge better relations with the Vulcan government, they asked the Vulcans for assistance. To accomplish this goal, the Vulcans dispatched 109 surgically-altered operatives who infiltrated various crime syndicates in order to topple the organizations. After the mission was accomplished, a majority of the operatives returned though several did not.
