Because Dewford is such an islandy kind of town, with water everywhere, Team Aqua decided that their hideout would fit perfectly here. It lies on the other side of the island, and the only way there is either by boat, by flying, or by surfing with a Pokemon. There's a boat that goes from the main island to this hideout, which starts on a little patch of land and leads to an opening that looks Pokemon-made from a distance. Down a tunnel and through a door, there is a secret hideout well below ground, with plenty of places for water-type Pokemon to stay, as well as humans. There's a bunker for the humans to sleep, a room full of cages and the likes for Pokemon to sleep, and even a lab, where newbies receive their starters. Enter at your own risk, of course.
