The Kiel-Saan deploy as a backup support unit, out of contact with the main covert unit, and wait in ‘sleep mode,’ never more than two, to maintain as low a profile as possible. They activate when H hour arrives, or when the situation goes awry and the main unit needs an exit. Then, the Kiel-Saan howl and inject the MetaChemistry drugs into their symbiont and there the covert part of their mission ends.
