The Xebec is the product of technologically advanced groundling cultures, an evolution of the Galley that derives its power from sails. Due to its adequate armament capabilities, it is actually fairly common in wildspace

The Xebec is the default craft for persons wishing to change residences, whether between planets or continents, being just the right size to reasonably carry a moderately wealthy person's goods. Those companies that rent such craft typically demand payment up front and flat out refuse to provide transport between crystal spheres unless paid very handsomely.
