|Horus Rising (Novel)
The planet was originally designated One-Forty-Twenty, signifying that it was the twentieth world to be encountered by the 140th Expeditionary Fleet. It was renamed after the last received transmission of Captain Khitas Frome, leader of the Blood Angels company that was the first Imperial force to land on the planet, and was soon wiped out: "This. World. Is. Murder."[1a]
Due to atmospheric turbulence, all landings on the planet became disorganized and individual shuttles easily became separated from one another, forcing the Space Marines to fight in relatively small groups while searching for each other. One such group, lead by Emperor's Children Captain Saul Tarvitz, discovered large rock-like structures that resembled dead trees. These "trees" had the bodies of several Blood Angels Space Marines impaled on many of the branches with a flying variant of the Megarachnids feasting upon the bodies.[1a]
Upon destroying a few of the structures, Captain Tarvitz discovered that they were what was causing the massive atmospheric turbulence and managed to destroy a number of the "trees",[1b] thus allowing a relief force of the Emperor's Children, and newly-arrived-Luna Wolves and the Blood Angels (including their Primarchs - Horus and Sanguinius, Imperial Army regiments and Titans of Legio Mortis) to land and begin a full scale assault on the hostile natives.[1c]
After a short, yet violent, campaign against the Megarachnids the forces of the Crusade were approached by vessels belonging to an advanced human society called the Interex.[1c] The Interex informed Warmaster Horus, that the Megarachnids and the Interex had once met in a massive war. Upon the defeat of the Megarachnids the Interex removed all of their interstellar travel capabilities and transplanted them to the world, which they called Urisarach. Their intention was for the world to act as a reservation for the violent and only semi-sentient species, one where they could live unmolested by outsiders, and vice-versa.[1d] So the Imperial campaign of Murder was officially stopped, provoking the anger and disagreement of some Luna Wolves (including First Captain Abaddon), but not changing the firm decision of that by Horus himself.[1e]
