'''===The Battle of Signus Prime''' is the main planet ===*{{Main|Battle of Signus Prime}}During the Signus Cluster, a tri-star system of seven [[Hive WorldHorus Heresy]]s and fifteen moons. Once a major industrial center, the System of Signus fell prey to Prime was the agents site of [[Chaos]] during an important battle between the dark days of the [[Horus Heresy]]. It became a [[Realm of Chaos]], a system of [[Daemon World]]s, Blood Angels and fell under the rule daemonic armies of Kyriss the Perverse, [[Greater Daemon]] of [[SlaaneshKa'Bandha]]. Kyriss raised for itself a vast palace on Signus Prime{{Fn|1}} After the battle, and its [[daemon]]ic horde rampaged across the system, utterly destroying hundreds of years of civilization entire cluster was declared ''morti perpetua'' ("forever dead") and annihilating several planetsquarantined.

In an effort to divide the loyalist forces, [[Horus]] had dispatched those [[Space Marine Legion|Legions]] who could not be swayed to his cause to the furthest reaches of Imperial Space, setting traps for them in the hopes that they would either be destroyed or too bogged down to assist the [[Emperor]] until it was too late. To this end, the [[Blood Angels]] had been tasked with the cleansing of the Signus Cluster, which [[Horus]] claimed to be under the control of xenos tyrants. [[Sanguinius]] had no reason to doubt his brother [[Primarch]], and so it was that he and his walked blindly into the snare set for them.{{C|1a}} Upon arrival in Signus, the [[Blood Angels]] were immediately beset by daemonic forces and the raw power of the [[warp]]. Many of the non-[[space marine]] crew went mad from exposure, and the Blood Angels were forced to detain them. In the midst of this, Kyriss the Perverse sent an image of itself directly into the chamber of [[Sanguinius]], daring the [[Primarch]] to attack. The Lord of the [[Blood Angels]] rose to the challenge, and unleashed the fury of his [[Space Marine Legion|Legion]] upon Signus Prime, personally leading his elite companies in an assault on Kyriss's palace. It was there that noble [[Sanguinius]] face [[Ka'Bandha]], [[Bloodthirster]] of [[Khorne]].{{C|1b}} ==Angel's Fall==[[File:Sanguinius and Ka'Bandha.jpg|thumb|right|200px|'''Ka'Bhanda''' fighting '''Sanguinius''' in mid-air.{{C|3}}]] As [[Sanguinius]] and his forces neared the palace of Kyriss the Perverse, a massive [[daemon]] the colour of dried blood rose to meet him. Its name was Ka'Bandha, [[Greater Daemon]] of [[Khorne]]. Ka'Bandha attemped to coerce Sanguinius to the cause of Khorne, but the Lord of the [[Blood Angels]] could not be swayed, and attacked the [[Bloodthirster]]. He dealt the [[daemon]] a vicious wound, but was in turn cast to the ground, his legs crushed by the coils of the beast's whip. As he watched, helpless, Ka'Bandha slaughtered his way through the [[Blood Angels]], killing over 500 of them. The massive psychic trauma knocked [[Sanguinius]] into unconsciousness, and unlocked something dark within the members of his Legion.{{C|1b}} ==Angel's Fury=Uncited= With the fall of their Lord and the butchering of their brethren, the [[Blood Angels]] were consumed by a dark rage that drove them into the [[daemon|daemonic]] horde with a berserker's fury. Signus Prime was utterly purged, with even the mighty Kyriss being banished back to the [[Immaterium]]. It was only after every daemon and cultist had been slain that the Blood Angels regained their senses. Their immutable wrath had left a shadow across the minds of the survivors, and Signus Prime became forever a place of darkness in their memories.{{C|2}} ==Sources==*{{C|1}}: [[Horus Heresy (Artbook Series)|Horus Heresy: Collected Visions:]] Volume II: Visions of Darkness**{{C|1a}}: Pages 171-2**{{C|1bUncited}}: Pages 176-7*{{C|2}}: [[Horus Heresy (Artbook Series)|Horus Heresy: Collected Visions:]] Volume IV: Visions of Death: Pages 340-1*{{C|3}} [http://www.blacklibrary.com/Blog/Where-angels-fear.html Black Library] ''Acessed (last accessed 8/1/2012'')
