Raiding of the Conduit Cities and their territory is common practice among many Ergon tribes. It is not merely for sport or plunder, although some enjoy these aspects. The purpose of the raids is to eventually destabalize and potentially destroy the conduit plants which draw energy directly from the Roots of the World and Primal Currents. Raids into smaller settlements or territory are made to train warriors, scouts, and shamans for direct assaults on the cities themselves, which are heavily guarded and very dangerous affairs. It is a mark of pride to kill a Stalker or Sweep Team agent and trophies are generally taken in the same way Sweep Teams and Stalkers take spears and elixir containers.
