Editing Solar System (section)

== [[Uranus]] ==
Uranus has no solid surface and its 27 moons were too small for permanent settlement ''(The largest: Titania is less than half the radius of Luna)''. Nevertheless, it was surrounded by a series of orbital cities populated by peaceful artisans called the '''Azurites'''. They built a stable warp route called the '''Elysian Gate''' allowing ships to bypass the normal Mandeville points in the Sol System. The main problem with the Warp Gate being built by the Azurites instead of being archaeotech is that unreliability of Warp travel is the ultimate reason for why the Imperium struggles to defend itself and stable routes would mean no need for Navigators. The Mechanicum would care more about not losing this tech than maintaining the Golden Throne. Of course, the alternative is that the tech ''is'' still known and used and that the Warp troubles actually are the result of Chaos constantly trying to disrupt the Imperium. Which may make more sense as Navigators use maps and routes which logically shouldn't even exist in the Warp, especially since the Imperium is the archenemy of what is basically the Warp's consciousness. There are also many instances in stories, games, and other lore of Imperial ships (or Chaos ships) appearing directly into planets' orbits. Which, shouldn't actually be possible with normal Warp travel and the ships should instead appear outside of the system and make their way to worlds within under thrust.

The Azurites peacefully agreed to become absorbed into the Imperium of Man, but were assaulted by pirates who initiated what would later be called the '''Unheard War'''. The Azurites petitioned the Imperium for aid and a force of fifty [[Imperial Fists]] were sent to provide support. The Space Marines quickly broke the pirate invaders within twenty minutes of battle, but as a parting gift, the pirate fleet fired boarding torpedoes loaded with psykers infected with a psychic plague called the '''Screaming''', which was contagious through sound and caused its victims to mutate horribly and die screaming.

As the only vaccination against the plague, the Imperial Fist forces purposefully deafened themselves and fought through the waves of mutated citizens to the station reactor and initiated a self destruct, preventing the plague from spreading any further. For their sacrifice, the Emperor ordered the [[Bell of Lost Souls]] to ring for the first time.

Despite the small size of its moons, they were heavily fortified during the Horus Heresy and acted as [[Rogal Dorn]]'s "Second Sphere" of defense during the '''Solar War'''. These forces were overwhelmed by [[Perturabo]] and a fleet of over 4,000 vessels brought through the Elysian Gate. The Imperial Fist fleet avoided engagement by sniping as many ships as they could from their fortresses and managed to hold off against the sheer number of invaders for around 36 hours before retreating, saving themselves for later engagements around Jupiter and buying more time to withdraw to Terra.

Uranus was only reclaimed during the [[Great Scouring]].
