D&D 4e Outpost 49

Conscripted into the great armies of Everar, you thought you'd be fighting the numerous orcs that have raided the land. Instead you were sent to Outpost 49, a small garrison of men who guard the passes of the Harking Mountains. This assignment overall is one of boredom say the regulars, but something strange happens mere days after your arrival. First it was the cook Jameson, then it was the stableboy Lucas, and then it was the herald Overton. All 3 of these men have vanished without a trace in the past 3 days. Despite an ongoing search to find them, nothing has been found. Commander Yester, has ordered everyone to stick together in pairs, in hopes of combating this issue and possibly finding out why men are disappearing. However, something needs to be done and perhaps Outpost 49 is not as boring as was thought...
