Not necessarily. If no one wants to play one they can always be NPC'd and doing their thing in the background. You can even make it a point of the game. Someone onboard is killing tech-adepts! they have to be found and stopped or else shit will go sideways real quick.

True or those pesky orks boarding the engine and killing the adepts inside. Both would be fun,
