Sentinel

A sentinel or watchman is one who stands at the gates of the city or in a lookout tower watching for incoming traffic.

In the EMPATH: The Luckiest Smurf story series, this role applies to both the Smurfs and the Psyches. In the Smurf Village, a few Smurfs are chosen to stand in the lookout tower for anything approaching the village during the day. At night, a Smurf is given patrol duty to make sure everything is nice and quiet.

In Psychelia, the role of the sentinel is given to the Psychelian Guard Elite, who also pursue after Psyches that flee from the village.
