A Jungle World is not an official Imperial planetological classification, but is a term in common usage among Imperial citizens for those planets whose environments are marked by a single, globe-spanning jungle across their entire surfaces.

Since the term "Jungle World" is not an official classification of the Administratum but simply a label used to describe the planet's predominant environmental feature, most Jungle Worlds that have been settled by Mankind are officially classified as Death Worlds, as the environmental conditions or extant jungle biosphere are usually extremely hostile and inimical to human life.

They stomped over clusters of defenders, pushing back though Imperial lines, and forcing the Catachans to make a tactical retreat into the holy shrines. The concentration of slaughter amidst the holy relics caused a rift to open in the fabric of reality, allowing a whole legion of Khorne's followers to spill out into the material plane.

This insidious plague infected every complex system and Imperial manufactorum on Comania, which had begun manufacting Daemon Engines for the Warsmith. The Space Wolves' arrival did not go unnoticed, and soon Harald's Great Company was set upon by the Daemon Engines that now infested the planet. A fierce war erupted between the Forces of Chaos and the Space Marines.
