Like the Advocates, the Sentinels were players who volunteered and existed to help players, and in the latter case, enforce the Code of Conduct; however, the Sentinels had considerably more powers than the Advocates such as the ability to teleport, mute and even remove players from the game world. 
Sentinels also conducted weddings in Dereth. Players could request a wedding via the events section on the Zone AC website and the Sentinels would portal players to the Wedding Halls and carry out the ceremony.
Sentinels could be identified by their special red robes and hats -- these items are unlike any others in the game and were available only to Sentinel staff. A Sentinel will also appear as a blue dot on your radar, similar to a lifestone indicator. You may see other avatars that look similar to a Sentinel but whose robes are of a different color. The green robe signifies a World Overseer, a person who monitors the Advocate program in that world. A purple robe signifies a Sentinel trainee, who is learning the ropes in hopes of one day obtaining the red robes.
In lore terms they were called Asheron's Order of Sentinels.
