An Era II technology exclusive to the Roving Clans which grants the ability to convert an army made up of Mercenaries to Privateers, which appear to all other factions as a roaming army. However, Privateers will have an increased upkeep cost, and cannot perform the Bribe, Parley, or Search army actions.
This technology replaces the Mercenary Corps technology that is available to every other faction in Era IV.
