Take the Cloud Station at 323, 284, -605 to Strifewind Isle. The Treasury is directly across from the Cloud Station at -60, -7, -549 .
To get to Granddaddy Strifewing upstairs at -170, 111, -1 , you first must kill Nagnag Strifewing. She is in the right-hand room (a nursery), which is the only on you can enter. Kill the fledglings first or they will all attack when you aggro her!
After she is dead you can enter the left-hand room and climb up the wall. Kill Granddaddy (in the room down the immediate eastern hall from your ascent) and the bot appears on the floor.
