Starting the Quest[]
Speak with Captain R.K. Irontoe in Kelethin, at ( 136, 112, 98 ) Copy/waypoint 136, 112, 98. He offers a great deal of lore, and many different conversation paths. After introducing yourself and exchanging common pleasantries, the responses that get you to the quest are as follows:
Gather 10 dwarven war artifacts found around the memorial. This is ground spawn and does not actually go into your inventory. (Note : as of 09/16/24 it appears you only need 1 artifact).
Look for the reddish sparkles and the mouseover infobox, orc scribbling, which mark the spawn. See the discussion page for more info.
By the passageway to Butcherblock Mountains, at ( 746, 14, -71 ) Copy/waypoint 745.99, 13.99, -70.57. He spawns on top of the root above your head, so look up if you can't find him. You may receive the message "The orc spy has not reached his post yet", which means you may need to wait a few minutes.
Along a branch leading off of Old Kelethin platform, at ( 155, 111, 79 ) Copy/waypoint 154.98, 110.85, 79.11.
Underneath Memorial Hill, at ( -178, 4, -15 ) Copy/waypoint -177.74, 3.71, -15.06.
Speak to The Mushroom King, at ( -145, -9, 142 ) Copy/waypoint -144.78, -9.38, 141.77.
Go to Tunare's Glade ( -252, 36, 363 ) Copy/waypoint -252, 36, 363 and:
Enter Crushbone Keep and inspect four chests inside the first room. If you're looking forward from the zone-in, two chests are on the right, and two chests are the left.
