In the era between the end of the Klingon Wars, and the War against the Tholians (the lost era of Star Trek..;), it was deemed necessary to have 'trainer' starships available to instruct larger numbers of Starfleet Academy (and additional units)cadets in actual experience commanding a ship in space. Simulations are all very well, but there's nothing like the vibration of a deckplate to let you know you're actually there. The Cadence Class was constructed as a simple but hardy ship, following in the traditions of pilot trainers for centuries. Consisting of a modified sphere, it housed the cadets and trainers during 2-week tours of the Alpha Centauri and Vega systems, doing simulated battles, emergencies, transports, away missions, and whatever was deemed currently necessary by Starfleet Command. Vickie 3, skin is Darlene (or Daria? I should writ e these things down), Charleston hair (had it, just never used it). Ships by me in Wings, background is Bryce and Mojoworld (that should be heretical enough..;). Have fun
