Merrek sends you to talk to Trader Darmlin at the docks ( 673, 24, 589 ) /waypoint 673, 24, 589.
I need to find Darmlin's helper near Felderham's Folly. His name is Helper Tjek and he can be found at ( -313, 150, 193 ) /waypoint -313, 150, 193.
After talking with his helper you need to find some good fruit (5 pieces). These are updates from trees that you can examine/pick in the area. You will also get rotten food that will not update the quest. (see note on talk page)
I need to return the fruit to Darmlin.
Return to Merrek ( 332, 194, 374 ) /waypoint 332, 194, 374. Merrek wants to see one of the bad fruit, so be sure to keep one!
Merrek wants me to search around the trees for anything out of the ordinary. You need to harvest a "totem". This tabable item will spawn randomly between the Quarry and the zone-in to The Estate of Unrest. It does not spawn only under the charred trees. It is also tiny (much smaller than it appears in the screenshot). Using the Track Harvestables ability looking for a "totem" works best. Alternatively, you can use a Gnomish Divining Rod to track it.
