Jack was a non-player character players could save during the 2013 Christmas event. He could be found playing on Musa Point during the event. The event involved freezing gublinches to rescue the kidnapped children. The Gublinch kidnapped the children to stoke the forges in their underground lair. If a player had completed the event, they would continue to see them playing at Musa Point.
- The two children, Jack and Jill, are a reference to the nursery rhyme Jack and Jill.
