In the time of the [[Great Crusade]], the world of Prospero was beyond Tizca appeared to be a desolatelush, verdant paradise.

When Magnus arrivedTizca's natural environment was warm, nestled amongst mountains and an ocean bay, and featured a river running through Old Tizca, he crashed suggesting a Mediterranean climate. Techno-psychic arrays built into the central plaza mountains of Tizca were used to reliably predict and control the cityweather's climate. The city was very vulnerable from attack from above{{Fn|2f}} Beneath Tizca's ventral mountain ranges, but no one seemed to notice this until the psychics of Tizca built massive hydroponic gardens{{Fn|2d}} while techno-psychic collectible arrays provided sustainable energy.{{Fn|13}} Under the orders of [[Leman Russ (primarch)|Leman Russ]] came and bombarded , [[the Censure Host]] began the planet.

However, slaughtering [[Raptora]] telekines protected Tizca from all he could findorbital damage, thus requiring the Censure Host to land on the ruined Prospero and commence a land invasion of Tizca. In the end, after a grueling duel between the two primarchs, Magnus cast spells that took all of the great city, his marines, and his precious libraries , to a new Homeworld, the [[Planet of Sorcerers]].{{Fn|2b}}
Later in the Heresy, the [[White Scars]] under [[Jaghatai Khan]] arrived to investigate what had transpired. They found no survivors from either side and the vengeful ghosts of slain Thousand Sons wandering the ruins of Tizca. The Khan was confronted by a shade of Magnus, who discussed both of their successes and failures and may have been tempting his brother to join the forces of [[Chaos]]. After refusing Magnus, Jaghatai then refused the newly arrived [[Mortarion]] and the two Primarch's battled as their fleets clashed in space. After a brief but intense battle between Astartes warships, the Death Guard disengaged.{{Fn|3}}

In the time of the [[Great Crusade]], the world of Prospero beyond Tizca was a lush, verdant paradise. Its landscape featured vast forests, wide open plains, crystal-clear rivers which flowed through its mountains, and the Prosperine oceans teemed with biological life.{{Fn|2d}} The surface of Prospero was abandoned by civilization, however, and was dotted with the remains of a long-dead culture. Empty cities, made up of hundreds of skeletal frames of iron and stone, were overgrown with forests and vines, while palaces were overrun with wild beasts.{{Fn|2e}}
After the majority of the planet's population was annihilated by the [[psychneuein]], the world became unsafe for life beyond the confines of the psychically-protected Tizca. Thus, the world outside Tizca's walls became known as '''The Desolation of Prospero.'''{{Fn|2a}}{{Fn|2e}} Tizca's natural environment was warm, nestled amongst mountains and an ocean bay, and featured a river running through Old Tizca, suggesting a Mediterranean climate. Techno-psychic arrays built into the mountains of Tizca were used to reliably predict and control the weather's climate.{{Fn|2f}} Beneath Tizca's ventral mountain ranges, the psychics of Tizca built massive hydroponic gardens.{{Fn|2d}}
The psychneuein, an indigenous species on Prospero, was a major threat to the early settlers of Prospero. The [[Thousand Sons]] theorized that, thousands of years ago, a warp-event triggered an explosion of uncontrolled psychic potential within Prospero's population, which in turn drove the pscyheneuein into a feeding frenzy, ultimately destroying almost all sentient life on Prospero. The only survivors fled to, and fortified, what was then-called “The Tizcan commune,” the last outpost of the planet's civilization. Tizca and its citizens continued to thrive, thanks to their ability to harness [[telekinesis]] shields that kept the psychneuein at bay.{{Fn|2d}} The psychneuein continued to present a problem to inhabitants of the world that would venture beyond the protective wards of Tizca all the way up to the end, when the planet's entire ecosystem was destroyed by planetary bombardment.{{Fn|2e}}{{Fn|2c}}
The psychneuein reproduced by implanting eggs into a host's brain psychically. An infected host would have no idea they'd been implanted until the eggs began to grow, causing severe pain and ultimately, death as the eggs hatched. On only one known occasion has a victim been successfully cured of the implanted psychic eggs. An archaeologist, living in Tizca, had been implanted while outside the city on a day trip. She later collapsed and was taken to a hospital where a team of highly skilled Thousand Sons Astartes were able to use their powers to remove the eggs from her brain in a form of psychic surgery.{{Fn|2}}

==Conflicting Sources==
Old lore described Prospero as a desolate, dark planet, where the only good thing about it was its remoteness. [[Mutant]]s and [[Psyker]]s were stated to have lived in reclusion and study. This interpretation of Great Crusade-era Prospero is no longer supported by more modern canon sources, such as *A Thousand Sons* and *Magnus the Red: Master of Prospero,*{{Fn|13}} which make clear the planet was a verdant world and that Tizca had an active social society, including cafes and restaurants, and was not merely a world of reclusive academics.
Similarly, this old lore described Tizca as being situated on the most central of the many mountains of the planet, though current places Tizca alongside an ocean bay, which obviously could not be true if it was located atop a mountain that was surrounded by other mountains.{Fn|13}}
