Harmony Island was a once peaceful place, run and inhabited by Monks. That is, up until it was overrun by Zombie Pirates! You must have started Great Brain Robbery, The quest to enter Harmony Island. To get to Harmony Island, players must speak to Brother Tranquility, located on the island of Mos Le'Harmless. Players must wear a diving suit to walk outside of the windmill during most of the quest, but it isn't necessary afterward. There is also an underground water tunnel where there is a fight during the Great Brain Robbery quest.

There is a Farming patch here, which is used to grow Allotments. Not many players use this farming patch though as it is far out of the way.

Players may use the Windmill to make flour. Most players do not use this Windmill due to the fact that it's very out of the way.
