The Decadent Sensorium occupies the upper four floors of a building in the Meridian Core that does not advertise its purpose. There is no sign. The lobby is a residential concierge service. You reach the Sensorium by appointment, by referral, and by having the Quanta to make your referral worth the host's time. It is, by most measures, the most comprehensive sensory experience venue in the GLMZ, and it maintains that position not through scale — it accommodates only twelve clients per session — but through the specificity and rarity of what it offers.

The Sensorium's primary product is borrowed experience. Through high-integration BCI delivery, clients receive packaged sensory recordings — not simulations, not procedurally generated approximations, but actual recordings of human sensory experience: what it felt like to taste a specific meal in a specific place in a specific year, what a particular body felt like in a particular moment, the precise texture of an afternoon that no longer exists anywhere except in memory. The distinction between simulation and recording is the Sensorium's central commercial claim and the source of its legal ambiguity. A simulated experience is entertainment. A recorded experience is a document. And documents, unlike entertainments, raise the question of where they came from.

The Sensorium's catalog is extensive. Culinary experiences from the pre-collapse era — meals that cannot be reproduced because the ingredients no longer exist, the kitchens are gone, the cooks are dead. Physical sensations associated with athletic extremity — not the edited highlight-reel version sold by mainstream BCI entertainment providers, but the complete unedited experience of a body at its limit, including the parts that hurt. Environmental recordings from places that are gone: the actual sensory experience of standing on a Louisiana barrier island in 2019, which is now 40 meters underwater. The catalog also includes interpersonal experiences, which the Sensorium discusses only in private consultation, and which represent its highest-margin and most legally contested category.

Clients do not ask where the recordings come from. This is a social convention of the Sensorium that functions as policy: asking is understood as a signal that you should not be there. The recordings come from somewhere. The people who supply them are compensated. Whether 'compensated' and 'consenting' mean the same thing in every case is a question the Sensorium's legal structure is built to make unanswerable. The host, who goes by the name Verity regardless of which body Verity is currently presenting in, has maintained the venue for eleven years and has never been successfully prosecuted for anything.

The experience rooms are individually designed. No two are identical. Each is calibrated to the specific recording being delivered — temperature, humidity, acoustic environment, physical furniture, and scent designed to eliminate sensory contradictions between the room and the experience. Clients who have described it say the disorientation is not in the body but in time: you return knowing exactly what you have experienced and unable to fully process that you did not experience it yourself.
