Holden was the caravan master on the journey from Hillsfar to Zhentil Keep. He belongs to the same orphanage network as Randall. He was last seen as the caravan entered Zhentil Keep right before the party was conscripted. He slipped the Zhents some money to secure a good position for the party. Which ended up being deep in the inner city on top of the Temple of Bane. Normally a very safe position, but not in this case.
