Thelka
From Tardis Wiki, the free Doctor Who reference
Thelka was a planet that was believed to be uninhabited. In the year 2495, it was colonised by Human due to the influence of a Aranjia advance party. The Aranjia arrived through a wormhole and eradicated the colour blue – even from the sky until the Doctor and Amy Pond’s intervention. (DWAM: Blue Skies Thinking)
