Wormhole of Calibri

From Tardis Wiki, the free Doctor Who reference

The Wormhole of Calibri was one of the best known wonders of the universe, with its dazzling array of colours. It was located near the planet of Hazri. It was used as a gateway for the Tulokons, who waged a nasty and very short war against the Hazrians. It was also the chosen site for an atmosphere bubble which the Hazrians used to house humans, a race so fearsome in appearance to the Hazrians that they hoped any further invaders would be repelled. Amongst the people captured and used as living "scarecrows" were Major Luisa Suarez, the Eleventh Doctor and Amy Pond. (COMIC: The Scarecrow)
