From the welcome screen: "This tinymuck is an adventure land for
those with brave hearts. It's not like your average muck in that
your character by their action may get changed in little or great
ways."

The name may imply it's an equine-centric muck, but it's not. Anyone
or anything is welcome. although a lot of the players take equine
based characters (horses, 'taurs, unicorns, pegasii etc). Unbridled
Desires prides itself on being a very open, relaxed atmosphere where
friends get together to just to get together. There are no "In
Character" rules, though you'll find that most of the inhabitants
are very real electronic extensions of their "RL" creators. While
online, the boundary between creator and created can become quite
vauge.
