Editing Macragge's Honour (section)

==During the Horus Heresy==

In the opening stages of the [[Battle of Calth]], the ship and its escorts were ambushed by the [[Word Bearers]] and its [[Daemon]] allies. The primary bridge tower was destroyed by a daemonic proxy summoned by [[Lorgar]], killing the ship's command staff and several of the Ultramarines' senior officers and blowing Guilliman into the void.

Under the command of Guilliman, Chapter Master '''Marius Gage''', and then-sergeant '''Aeonid Thiel''', the daemonic invaders were banished back to the Warp and the Word Bearer boarding parties repulsed. Guilliman then led a force of fifty Astartes in a teleport attack to confront [[Kor Phaeron]] and his [[Possessed|Gal Vorbak]] on the orbital platform they occupied.

The Word Bearers were eventually forced to flee on their flagship, the ''Infidus Imperator''. Guilliman ordered Gage to pursue the traitor flagship, which led to a running battle between the two warships. At great cost, the ''Imperator'' was destroyed (which among things, involved the sensor-blinded ''Honour'' [[Awesome|homing in on the teleport beacon of the sole remaining Ultramarine Terminator still alive that was still fighting]] of the scores that initially boarded the ''Imperator'' to aim its lance batteries), but the ''Honour'' was left in the warp without an accurate way of getting home, meaning none of the surviving crew had any idea if and when they would return to Macragge.

It somehow survived its ordeal in the warp, but by the time it managed to limp back into the Ultramar system, the Horus Heresy was long over, and the battles of [[Great_Scouring|the Scouring]] already fading from memory. (This is depending on the writer ; one piece of fluff detailed its use during the Scouring, along with Marius Gage resuming his duties, which is a bit odd considering Guilliman used a different ship during the battle at Thessala).

The ship was eventually repaired, but it never served in an active capacity in the Ultramarines fleet. In the ten millennia since then, it had become a shrine of sorts, a sad relic of a much brighter time.
