Society of Sensation
The Society of Sensation, also known as the Sensates, are a Faction in Planescape defined by their belief in the power of the senses and the value of experience. In short; the multiverse only exists in so far as you have experienced it through the powers of your own senses, and the purpose of existence is to experience as much as you possibly can.
This is not simple hedonism; the Sensates don't approve of those who just want to wallow in indolent pleasure, and actually have a special prison where they abandon those who commit to the Faction only to indulge themselves. No, a Sensate is an explorer, somebody who wants to know everything by feeling everything, pleasant or unpleasant. They're not suicidal, but they concern themselves with the now and regard inhibitions as a dirty thing.
Whilst they may be looked down upon by the more grim, stoic or ascetic Factions of Sigil, the Sensates are hugely influential, as they have the ultimate control over the city's entertainment business.
