To reach the farm, start from Jokanur Diggings, enter Zehlon Reach and head north to where the quest marker is located. Speak to Muenda and then click on the Warped Chest nearby. After opening the chest, map travel to Kamadan, and enter the Plains of Jarin. Go a short distance roughly north to the Mound of Dirt. After reading the message, return to Chago for your final reward in this quest chain.
