Riftwardens

The Riftwardens are a loose collection of planar travelers, from all over Golarion, who are rumored to be guardians of the Great Beyond. They seek to prevent others from using planar gateways for dangerous ends and punish any whom they catch doing so. They oppose a rival group, the Blackfire Adepts, whose goals are opposite their own.

Riftwarden members identify themselves by the Sign of the Seeker's Spiral.

Status
The existence of the group in Kenabres has long been rumored but never publicly proven.
