Dialogue
 * "When Duke Barradin and the rest of the Vanguard broke through the Charr lines to Piken Square, they were unable to take much in the way of supplies. Supply columns have been heading out to Piken Square with regularity, but I have just received word from Quartermaster Aada that the latest column is at least a day overdue. The duke must have those supplies if he is going to hold out against the Charr! If you are heading to Piken Square, can you discover what has happened to the supply column?"

Reward Dialogue
 * "You're the one who led the missing supply column here? My men and I owe you a great debt. Good luck to you my friend, and my whichever gods you pray to watch over you."

Walkthrough
Go through The Breach and bear left along the tar river. You'll find a Charr boss and a bridge. Cross the bridge and follow the path. You'll have to go around left and then cut back through the hills to find the lost supply column. Each of your party who is doing this mission must touch one of the supply column members so that it will complete when you get to Piken Square. Once you gather the units just follow the green arrow and lead them to Piken Square without letting all of them die.

Bug
Occasionally, after collecting the supply column, if you return to Piken from the west, the column will despawn and you will be unable to complete the mission. This does not happen every time, but is avoidable by simply entering from the south.
