Scene Sariel Scarlet Marpenoth ( View full size )

In late 1493 DR, Sariel and her new friend Zelifarn descended deep into Deepwater Harbor. Near the bottom, over one hundred feet below the surface, the two found a strange metal vehicle being operated by drow.
  The vehicle turned out to be the Scarlet Marpenoth, a Lantanese-Gondish sumbarine stolen by the drow mercenary Jarlaxle.
