Necros was a remote world situated in an outer arm of a galaxy colonised by the Humans of Earth during their major expansion era. While habitable, the planet was too remote to offer strategic importance and contained no great mineral wealth. To this end, the planet was largely ignored by the galaxy at large. A number of food suppliers were based on the planet, however. The planet's lack of population meant it was an ideal location for the funeral parlour and suspended-animation facility offered by Tranquil Repose.
Necros was ideal for colonisation by the Humans because the atmosphere, gravitational pull and native vegetation were all remarkably well suited to their needs. No indigenous intelligent native population had evolved on the planet which meant that colonists could move in undisputed. In general, the planet was colder than Earth, being slightly further from the system's star.
The planet had a varied eco-system with a variety of plant and animal life – much of which was suitable for human consumption. Since famine was the major problem faced by the spreading colonies, a number of food production companies saw an opportunity and established factories on the surface to help resolve this problem ... for a price.
Unspoilt until Humanity expanded to Necros' vicinity, a varied eco-system had developed without interference by "intelligent species". The planet's geography was varied – mountains, plains and forests being the major land-types. For much of the year, the plains were covered in a broken layer of snow.
Since humanity's arrival, the planet was primarily used the base of a number of food production plants as well as Tranquil Repose – a funeral parlour and suspended-animation service for the cream of society.
The overriding idea behind Tranquil Repose was that a deceased body would be prepared for funeral and the funeral held on site. The body would then be placed in suspended animation beneath the planet's surface until such a time as the cause of their death had been cured and the body could be revived. Clients who were critically ill could also receive the same treatment – though with a higher chance of revival.
Unknown to the galaxy at large, the funeral parlour had been taken over by Davros. The Kaled scientist was using the bodies held in perpetual grace in his own experiments. Firstly he was endeavouring to create a new Dalek army that would be loyal to him only. Secondly, the scientist was using the bodies to produce a high protein food stuff which he sold to developing worlds through one of the companies based on the planet.
Following Davros' capture by the Daleks and the facility's destruction, the site of Tranquil Repose was rebuilt as a food production facility. A plant common to the area that had been used as decoration by the funeral staff was in fact extremely high in protein and could be converted into a valuable food-stuff with little effort.
