Lieb

 is a deckhand on The Stormcap. As an NPC, is played by Matthew Mercer.

When the Mighty Nein pirated The Stormcap while traveling to Darktow Isle with Avantika aboard the Squalleater, Jester Lavorre requested that one crew member of The Stormcap be sent over to their ship. Captain Jules Arog sent Lieb, who was given a tattoo of "The Mark" (a googly-eyed smiley face with tusks, representing Captain Tusktooth) by Jester. Lieb was sent back to The Stormcap after the Mighty Nein had plundered the ship.
