Green Guards

Green Guards The Green faction of the Circle of Seven of Avondur. The Green faction, unlike the others, appears to have only one member and one representative, the Sentinel of the Rifts. Even though the Old Contract speaks of the Green Guards in plural form. Little is known about the Green Guards. The Oasis at the entrance to the Desert of a Thousand Doors is where the Sentinel can be encountered.
 * One group of the Seven Circles of Avondur.
 * Place: Gateway Oasis
 * Leader: Sentinel of the Rifts

The Sentinel of the Rifts has been on Avondur before Corflic and the Orlan arrived"

"It is said, he is the only one remembering the First Empire . As much as I like to be known as a person with great knowledge about these things, I too only rely on stories and hearsay about the Sentinel, but I know he is not associated with any of the Seven Circles[1]. The sentinel lords over the oldest rifts. The ones in the Desert of a Thousand Doors ".

[1} This is where Ciferus is wrong, the sentinel represents the Green Guards and is indeed a member of the Seven Circles, he just never participates in any meetings etc.
