Tranquility Base
Non-descript, somewhat run-down, and generally boring by daylight, this side-street lights up at night. Crowded and sweaty, nearly every surface of the ally has been encrusted in some kind of bright neon, the palette composed primarily of deep, carnal reds and cool, almost minty aqua. Here, one can find every kind of food and drink; here, one may engage in any seedy aspect of the underground world of man and ninja; here, you may seek any pleasure, any primal joy available to the flesh. And here, in this cluttered and threatened back alley, prominently featured, is a fabulous onsen.
Next to a noodle bar and a pawn shop, across from a fancy night club, stands a stone structure lacking any of the neon flare of the surrounding establishments. Above the entrance, a lapis lazuli effigy of a smiling tengu is half visible, some 15 meters into the air. From the open, smiling mouth pours a constant flow some unknown kind of thick silvery mist which cascades down to the ground in thick sheets, completely obscuring any glimpse of what lies within. Many of the more prominent establishments here have conspicuous security guards present, and yet outside the mist there appears no guards.
This, is the Tranquility Base.
Floor 1 - Onsen
Once clearing the thick, cooling mists, customers are greeted by a small, tidy reception area in which each attendee shall receive a locker key and a thick, plush bathrobe. To the left is a women's changing area; to the right, a men's, though the distinctions are unenforced. From here, one can enter the onsen proper, a large, central and naturally occurring hot spring for mixed gendered use. Alternatively, two separate gender-restricted chambers exist as off-shoots from the main spring for the shyer among us. Connected as well to the main spring, for those wishing to melt their worries away, lie a set of huge, marble steam rooms in radial symmetry, available in 3 different temperatures and once more set aside with 3 for the men and 3 for the ladies.
Though the entrance to the base is relatively unassuming and crowded, the hot spring makes it plainly apparent that nearly the entirety of two full city blocks have been carved out to accommodate the lush experience of the Tranquility Base. Light fare and drinks are all available for purchase to enhance the experience of the patrons.
Floor 2 - Spa Services
Above the quiet chatter of onsen and its serene sound of bubbling and pattering water, the second floor of the Base has a collection of private rooms for individual and small group uses. Here, the majority of the spa services are available - save the actual enjoyment of the rejuvenating waters. The rooms are also available for private meetings of nearly any purpose, and soundproof options as well as personalized security details may be purchased. Thus, one may come to floor 2 for a special business meeting, for the exchange of illicit human organs, or to enjoy a soothing skin massage.
Floor 3 - Vacant
Currently closed to the public
