Looking for a Lost Son is a Timed Quest in Xenoblade Chronicles. It can be received in Alcamoth from Vol'aren, who needs to find his son Atael. If Riki is in the active party, he will comment. Atael is not necessarily in the same location each time, but he always seems to be in a corner of some sort. Atael can be found in the corner all the way east and slightly north from the Fountain of Hope landmark at 12:00. It is possible that his location varies with time of day.
