|This article is about the planetary classification, for the Imperial Guard novel by Steve Lyons see Death World (Novel)|
A δτ-class or death world is a planet in which the native flora and fauna has evolved into naturally aggressive and dangerous forms. These eco-systems are finely balanced between continual destruction and lightning-fast reproduction. Death worlds take many forms, ranging from jungle-covered hell-holes with carnivorous plants and animals to barren, volcanic wastelands racked by ion storms.
Humans can, and do, live on these worlds, but it is a never-ending struggle. On many death worlds it is as if the entire bio-mass of the planet were consciously motivated against human settlement - concentrating forces against intruders to destroy them.1 Death worlds with human settlements or colonies can have populations of 1,000 to 15,000,000.
Death worlds are not usually inhabited, and are nearly impossible to colonise but still need to be explored, which means the establishment of outposts and other support facilities. Some planets have rich mineral wealth, animal life, vegetables or gases, so tithes might range from Solutio Tertius to Solutio Prima.
