Covered with jungle vegetation, these islands have a type of tropical strangler-vine which grows in lattices up trees, eventually killing them but leaving the latticed outline in thick and woody vine. In some areas, the vines grow across narrow inlets between islands, connecting them incredibly securely. The large nut inside the edible green fruit contains a central compartment full of thick, whitish oil. There is very little current around the Seven Sisters, though offshore to both the east and west are powerful northerly currents. Animal life here is plentiful and very diverse. The most dangerous creature on them are tunnelsnakes, some of which are large enough to attack humans and very young dragons.
