The Sentinel forces watch over planets and protect them from damage. They are robots that fly around, and monitor wildlife. They are alerted by environmental damage, and attack if they see continued abuse of natural resources. They require obedience.

This is a Sentinel Summoner Drone. They can summon light Sentinel reinforcements every 2 minutes. They stay to the sidelines of battle. They have limited sentience.

They can only say “THREAT DETECTED”, “SEARCHING”, and “SENTINELS DEPLOYED.”
