Rutgar Glyphshaper at Bronzebeard's Encampment wants you to deliver the Glyphed Crystal Prism to Geologist Larksbane at the Cenarion Hold in Silithus.
We're on the verge of a breakthrough, [player]! The rubbings you recovered have allowed us to recreate the glyphs on this crystalline prism. They are apparently a means for the Qiraji and other unknown entities to communicate various messages to the silithid.
Unfortunately, that is all we could get out of the glyphs. We need to find a way to unlock the messages hidden within the crystals.
Take the glyphed crystal prism to Geologist Larksbane at Cenarion Hold. She might be able to help.
