there are three classes of vell-os 'ship'; darts, arrows and javelins, in order of power. vell-os 'ships' are not ships in the common sense. the psionic power of the vell-os pilot forms the shell of the vessel. the ship is also powered by the pilot's mind, and all defenses come from the pilot. the ship is literally an extension of the pilot within. while the ship does not have very powerful armor, the shields and weapons are some of the most powerful in the game.
