Necros

Necros, alternatively spelled Nekros, was a human-colonised planet and the location of Tranquil Repose, the finest funeral home in the galaxy. (TV: Revelation of the Daleks)

It was a Class-M planet orbiting a G-class star. Upon materialising at the southern end of the Eastern Pyrenees in 1242, Bernice Summerfield commented to the Seventh Doctor that it looked like Nekros. (PROSE: Sanctuary) The planet was cold, and home to the predatory voltrox and speelsnape. The weed plant was the only plant that grew on Necros and provided protein when refined.

Blue was the official colour of mourning on Necros, and women's legs were to be covered at all times. In addition to Tranquil Repose, Necros was also the location of Kara's food-processing factories, which provided food for starving planets as famine was one of the major problems of Necros's part of the galaxy.

Davros, calling himself the "Great Healer," took over Tranquil Repose to create his Imperial Daleks from the Resting Ones, using the rejected people to create a highly concentrated protein and turning them into the food for Kara's factories. Eventually, the Renegade Daleks were summoned and took Davros away for trial. (TV: Revelation of the Daleks)

Behind the Scenes
Although Revelation was never novelised by Target Books, the NZDWFC/TSV did release a novelisation. In that version, Necros was the 7th planet of the Pherra system, one of the Pherran colonies established "centuries ago" in the early 30th century.
