Well, I found one. It is at the altar on the Qa Riverbank by the Neamsog Bunkers. If, after you activate it, you select the stone again, it pops up a menu;
- Select the Rone of Kojan
- Select the Rone of Qalia
- Select the Rone of Thestra
- Select One Way Rifts
They each provide a submenu with three teleport options.
