The Corvette

Sentient spaceship outside of space and time.

The Corvette, in the Blur

The Corvette is a sentient spaceship 36 miles wide and 42 miles tall. It is a shiftship, capable of traversing higher dimensions and the Blur, which is the "space" between alternate universes. It is also capable of opening portals between itself and any alternate universe in its vicinity.

The height of the Corvette's interior rooms and corridors is typically between 40 and 45 feet, but it also has spaces which are considerably larger. The mast of the Corvette contains most of the ship's habitable space; the ring-shaped section contains the ship's propulsion, navigation, and weapon systems.
