Redbow Isle, Redbow or Redbow Island is a barrier island close to the Nalt's Island in the Shackles. A dangerous tribe of vegepygmy natives live on the Redbow. They use to launch attacks at any ships that dare pass through the straits between Redbow and Nalt's Island. Their strategy is to force unwary ships toward the whirling vortex beneath Whirlpool Rush on the straits' far side. The vegepygmies make their characteristic gleeful clicking noises during their assault.
