A large cavern has been hollowed out under Hogyoku hill with a few, smaller hallways branching off it which go to places like the changing rooms and the hot springs. It’s always day and has a extremely strong reiatsu seal around it, keeping any reiatsu users reiatsu hidden completely.

The hot springs heal any wounds and replace reiatsu at a slow but noticeable pace. These hot springs are hidden away from he main cavern by a short, curved and well-lit hall. There is a spring for Males, a spring for females and a spring for those who don’t mind bathing with the other sex.

The changing rooms are smaller, natural caverns that have winding entry ways on either side of the training grounds entrance. They both have changing stalls for shy or self-conscious members, a set of shower stalls, toilets and rows of hooks down the middle of the room to put clothes, swords or bags on.
