>>55013074The Hyperbolic Time Chamber is a pocket dimension where time passes extremely slowly in relation to the outside world. One day outside is one year inside. Once you're in, you're stuck there until the year is up and the door opens again. Food and water is automatically provided for you, so you will survive.
It's commonly used by martial artists who wish to refine their skills extremely quickly, as it lets you get in a year's worth of training in one day.
