Help with 3 Tests in Augury Rock

Can anyone tell me where to get the blessing to make the freaking rock teleport me? I have run around the lake around 3-4 times and can not seem to find it. The guy named Lord something said to get the blessing from Thrisy River, but I cannot seem to locate it either.

Thanks, Any help is much appriciated.

You have to complete the three missions (Elona Reach, Dunes of Despair, Thirsty River) in the desert before you can activate the stones at Augury Rock. Consult a map to find the missions: http://www.guildwarsguru.com/newmap
