Sentinel Faction Guards are Sentinel NPCs who guard key areas. Two unnamed Sentinel Faction Guards stand at the gate to the Sentinel Encampment in Avant Gardens. They defend the camp by firing their rifles at any Stromlings that wander too close to the gate's entrance. They have no missions or dialogue and remain only background characters who protect the encampment. In Nexus Tower, there is a Sentinel Faction Guard named Bullet Mullet who is positioned in the Sentinel War Room. However, aside from his title, he has little in common with the Avant Gardens Sentinel Faction Guards.
