The skilled leaders of the Riverguard are known as Sentinels. They are given responsibility for whole river basins or lake systems. It is their duty to relay all news to their Neritican superiors, and they are regularly visited by the royal envoys of the Trident Realm in order to make their reports. Sentinels are regularly drawn from the clutches of the Dambusters, some retaining their massive mounts and leading whole armies of the Trident Realm to war.
