The Keepers

The Keepers are a somewhat mysterious race that are apparently responsible for the construction of the Sphere. They have surprisingly simple motives in abducting the inhabitants or earth and thousands of other worlds. This race seeded thousands of worlds in the past, including earth for the simple purpose of harvesting whatever evolved upon these worlds for whatever was needed at the time, be it warriors or food.

Appearences in the Prey
The first Keeper appears in Level 11: Hidden Agenda. As Tommy walks through the corridor he catches a glimpse of fleeting Keeper. Later in the same level he sees a another Keeper jumping from portal to portal. In Level 12: Jen a Keeper calls to Art Bell and announces that the Dark Harvest is at hand. In Level 13: The Dark Harvest one Keeper attacks Elhuit and then dissapears. In Level 20: Facing the Enemy Tommy fights a group of Keepers. This is the last level in which Tommy fights or sees the Keepers.
