The Fourth island is called Iskip and is basically just a giant, dead volcano. Nothing green grows on this rock jutting out of the ocean. Some archeologists say this is the island that destroyed the ancient kingdom on Rosh, but there's no proof of that. A large serpentine dragon makes its nest in the caldera of the volcano, 2000 feet above sea level. The dragon is protected from outsiders trying to heroically kill it (yeah right) by a cloud of poisonous gas that never leaves the caldera. In fact, the gas comes from a cavity of methane deep underground and escapes through small fissures.
