Clean the two dusty malmstones found along the road near E-Tatt's Spire.
You have scrubbed the grime from the dusty malmstones. Report to Q'djawana at Treespeak Stables.
With a decline in the number of trees suitable for egg-laying, monsters have taken to depositing their unhatched spawn on and around the dirt-encrusted road signs. Q'djawana is yet to settle on a method to prevent the malmstones from becoming substitute nests, but thanks to your efforts the problem has been forestalled for a short while at least.
