bDv TrekMUSH is an old-style text game. It is Trek-based, taking place around 2162. The United Federation of Planets doesn't exist yet, and the technology level is comparable to that of the Enterprise series.
Currently it is possible to join and RP in five Factions, the Terran Confederation, the Rihannsu Stelam Shiar (Romulans), the tlhIngan wo' (Klingons), the Vulcan Federation or the Andorian Imperium.
The game environment spans countless rooms spread over dozens of planets and asteroids, as well as space stations and starships that can actually be pitted against each other through the Aspace system.
Presently the Terrans are coming too from having just barely avoided open war with the technologically more powerful Klingon Empire and the first Player Characters have been chosen to lead their Confederation. The Klingons have allied themselves with the Tellarite Worlds and the Romulan Star Empire, which sits patiently observing all parties from its cloaked vessels, waiting for an opening. The Andorian Imperium recently annexed an Orion asteroid base and plans to settle a Rogue Planet within sensor range of their home system. The last heard of the Vulcan Federation concerned the rather sudden death of one of it's liaison officers to Earth, who's ship got destroyed trying to break a recent quarantine of the Sol system.
The number of places in each faction are limited - 50 each for the Andorians, Vulcans, Romulans and Klingons - and only 40 for the far more popular Humans and Denobulans of the Terran Confederation. I make this post cause particularly the other empires, the Vulcans, Andorians, Romulans and Klingons are in need of new active players to further the interaction between the different empires, and keep the game interesting for all.
I invite all who are interested to check out - http://www.bdvmush.net - and - as a personal favor to the great guy who directed you there - remember the funny blue people with the antennae.
