Tyche's cabin (#19) is the cabin that houses the Greek demigod offspring of Tyche, goddess of luck and fortune, at Camp Half-Blood. It has an unknown number of occupants, as the cabin was not constructed until after The Last Olympian and was not mentioned afterwards. Such cabins are confirmed through an interactive map of Camp Half-Blood found on Rick Riordan's official website.
According to Rick Riordan, the cabin looks like a miniature Las Vegas casino. Inside, there is a main sitting room with two built-in cushioned benches that double as beds and storage space underneath. There is also built-in, programmable furniture that can be collapsed, moved and reshaped; with the snap of their fingers, the living area can be turned into a bedroom, gym, dining room or military command center. There is also a dozen preprogrammed interior-decorating schemes and state of the art bathrooms with large showers. A narrow staircase leans against the back wall that leads up to the lofts with two more twin beds and extra built-in storage underneath the stairs. The loft can also be used as a meeting area, game room, whatever the campers want.
