Trammel's island was a floating island on Dorumaa that was used by Rufus Trammel as his base of operations on the moon. It was made up of many different skiffs and ships that had all been hooked together, although they were all still functional, so the island could be dispersed at a moments notice. It floated abput 10 meters above the sea and was fitted with extensive security systems. He also had some of his poachers carry out regular security patrols on it. Trammel once sent out some of his men from the island to transport the Dorumaan leviathan Jessel and his meeting was secretly watched by the Heroes of Cularin. Afterward, the heroes rescued the Kel Dor scientist A. Rahring from the island.
