Nautiloid

The preferred ship of the Illithids (Mind Flayers). These vessels are grown from disgraced illithids mutated by a powerful psionic ritual. The victim's intelligence remains intact within the ship's core. These condemned souls serve in hopes of redeeming themselves and returning to their original form.

Being intelligent, the ships can operate themselves, making them dangerously responsive. They do not require sails, being able to steer psionically. This allows them to make turns and perform tight maneuvers impossible for other classes of ships.

The downside of intelligence is that, like all illithids, the ship remains ambitious, cunning, and ruthless. On the off chance this disgraced mind sees a better deal than its passengers can grant, it will not hesitate to turn on its crew.
