Enies Lobby

A government-controlled stronghold filled with 10,000 soldiers and the second strongest cipher pol CP9. The island has a courthouse, which makes it easy to transfer high-level criminals through Enies Lobby and directly into Impel Down, or to the Marineford. Enies Lobby has extremely strange oddities that many islands are not known to have. Among them is a large waterfall under the island, leading to nowhere except a huge black void, although there is water down there. It is an island connected to the sea train.
