Spelljammer

A type of magically powered vessel that can travel great distances, even into the Sea of Night. each ship had a magical helm or "captains-chair" that allowed a suitably poweful mage to pilot the ship.

Many of these vessels (and vessels like them) still existed on Faerun prior to the Spellplague. The Elves of Evermeet maintained a small fleet of them, while the derivatives of these strange and mighty vessels could be seen flying openly over the southern nations of Nimbral and Halruaa.

The status of these otherworldly ships remains unclear in the post-Spellplague world.
