Barterer

The game also links it as Barterers.

From the game's encyclopedia

Wanua Rulers can Barter by raising their Armies as Barterers. They work similarly to Raiders, except that they will not be Hostile to the Holder of the targeted Holding.

Raiding Armies of other Rulers can fight Barterers and steal their Loot.
