Harfolg was an elderly Vatrexii who owned the Begins at Home. When the Dog Pirates attacked the ship in early 2000s, Harfolg was the last member of the crew to survive.
Two weeks after the attack, he was found by Iris Wildthyme, Panda, and Simon. In his dying breath, Harfolg told them about the attack and how the dogs had wanted a jar. (PROSE: Enter Wildthyme)
