Inspect (click) the rune-inscribed stone in Twark ( 137, -240, -861 ) /waypoint 137, -240, -861. It is a small squarish stone to the right (south) of Vhesh. It's important to click it, not just accepting the quest update when you are close to it
Inspect another rune-inscribed stone in Twark. ( 103, -173, -831 ) /waypoint 103, -173, -831. On the ledge just above the first one. Not on top.
Inspect another rune-inscribed stone in Twark. ( 65, -165, -738 ) /waypoint 65, -165, -738. At the foot of the tree.
Inspect another rune-inscribed stone in Twark. ( 244, -179, -740 ) /waypoint 244, -179, -740.
