The Plume Island is situated under the Ruby territory and its cavern walls are illuminated by scarlet light. The island itself has a small harbour where boats are tied to huge, scarlet fungus with branching segments. Near this habour there are hills covered with red and brown fungus trees, some of which were broken and uprooted by The Fear producing gigantic waves. FIelds also lined the area around the harbour with some sort of crops growing. Beyond this shore is the Plumes' actual village surrounded by a low wall, with houses that were dark red or brown, and divided by streets. At the end of the village was an open space which finished onto a high wall with a complicated pattern of red stones.[1]
After the Plumes rescue Lief, Barda, Jasmine and Glock from drowning, they were held captive at the end of the village in a cage and were to be offered as sacrifices to The Fear.
