The Irontoe's have been around for centuries

1. Head to Greater Faydark and head up the acorn lift to find Captain R K Irontoe ( /way 135, 115, 100 ) in Kelethin. Click through his long rambling stories about dwarves and he will finally give you the quest.

6. Next head to NW tent on Orc Hill ( /way 295, 60, -140 ) and examine the chest.

7. Head out of the tent and into the second one of the left. On the floor at the back is a Scroll you need to examine.

This is the 2nd spy. He spawns up high above the zone line to BBM

8. Click on the Gong to the right of the chest in the tent and this will spawn three spies:

The 1st Spy ( /way -175, 15, -15 ) is near Memorial Hill on a branch.
The 2nd Spy ( /way 745, 10, -75 ) is found high up on branch at the entrance way to Butcherblock Mountains.
The 3rd Spy is located up back where Irontoe is in the tree city on a branch.

N.B If a spy does not spawn when you approach someone might have recently killed him. Respawn is only a few minutes.

The Mushroom King surrounded by The White Cross
