Dead End

From the introduction:

This encounter takes place in a dead-end alley in which the Red Kings have prepared an ambush. The characters could be their intended targets if the PCs are known to be in Merywyn and carrying valuable goods or if they have been targeted by any faction of the Llaelese conflict and a contract placed on their lives. Alternatively, the characters accidentally stumble into an ambush the Red Kings set for an unrelated target.
