The '''Fifth Fellowship''' of the [[Thousand Sons]] [[Space Marine Legion|Legion]] was active during the [[Great Crusade]] and [[Horus Heresy]].{{Fn|1d}} Led by [[Sul Kontep]], a large part of the unit was able to escape the [[Burning of Prospero]], and later surrendered to the [[Imperium]]. As the Fifth Fellowship's members still considered themselves loyalists, they were allowed to fight for the [[Emperor]] in the [[Horus Heresy]] under the supervision of [[Sisters of Silence]] led by [[Ambriel Malineux]].{{Fn|2a}}{{Fn|2b}} The Fifth Fellowship was largely destroyed in the [[Siege of Cthonia]], though its remnants were subsequently considered redeemed and absorbed by the [[Imperial Fists]].{{Fn|2d}}{{Fn|2e}}

== History ==

By the Imperial attack on [[Prospero ]] in 004.[[M31]], the Fifth Fellowship had been depleted in strength due to a number of previous operations. A number of its companies were still engaged in operations across the [[Galaxy]], with about 6,200 Space Marines of the Fellowship being based on Prospero at the time.{{Fn|1a}} Much of the unit was located at [[Tizca]]'s [[Valperine Bastion]] when the Imperial [[Censure Host]] invaded Prospero; there, it fiercely resisted and survived the initial battle. However, when mass-[[flesh-change]] erupted in the Legion over the course of the battle, the defense defence of the Valperine Bastion collapsed. Regardless, elements of the Fifth Fellowship under a line officer, [[Sul Kontep]], survived and hid in the bastion's ruins using psychic kine shields. When Primarch Magnus escaped into the [[Warp]] and the Imperial forces began to organize mopping-up operations, Kontep's troops broke out of their hiding places and quickly gathered supplies, refugees, aircraft and [[Grav Vehicle|anti-grav vehicles]] amid the ruins of Tizca. Before the Imperials could muster a response, the Fifth Fellowship fled onto Prospero's sea.{{Fn|1b}}

Kontep's forces only reemerged once the victorious Censure Host was in the proccess process of evacuating Prospero. Using some manner of powerful divination, the Fifth Fellowship staged a well-timed assault, capturing three [[Imperial Army]] [[Transport Ark]]s and fleeing into space. Due to the Censure Host's fleet being dispersed around Prospero's orbit, the Transports were able to reach the outer regions of the [[Prospero System]]. While one transport was eventually destroyed by the Censure Host's destroyers[[destroyer]]s, the other two manged managed to escape their pursuers. However , since the Transports transports lacked [[Warp Drive]]s, the Censure Host did not commit a concerted search for them and soon left the Systemsystem.{{Fn|1b}}
