The night of the Convoy Mission

We were to infiltrate one of the Empire's Storage Outposts. This simple in and out turned to a massare (for the empire's soldiers) by the contents of a seemingly normal box. It was dark, but an even blacker darkness somehow attacked? We quickly left, but the Empire is not the only enemy in the forests.
An owlbear took chase. An unholy miracle took place then; in a wrong turn the thicket cleared, and a sword lay there. I felt it resonate with me somehow, and there I was, saved.
By a hair's breath I escaped another fateful encounter that night, Frederick himself was patrolling the woods.
