Briggan & Harry are crewmen onboard the Setting Sun, a pirate ship captained by Captain Longlegs. Harry stole some magic from a Dark Faerie, and when Captain Longlegs sailed them into a storm, Briggan used it. The magic teleported them to Meridell, where a farmhand named Jimmy agreed to guide them back to the sea in exchange for becoming part of the crew.
One of them appears to be a Blumaroo, and the other a Mynci, but it is unknown which is which. They appeared in issue #6.
