Editing Hive Fleet Colossus (section)

== Chronological problems of Colossus ==

Hive Fleet Colossus is one of the oldest hive fleets mentioned in the fluff, not only because (in theory) they are one of the oldest [[Tyranid]] fleets around the galaxy, but because they are one of the earliest mentions of Tyranids by GW as a whole. As such, there are problems with a decent amount of their lore. In theory, the first sightings of Hive Fleet Colossus were around M28, between the Ultima Segmentum and the Segmentum Tempestus. This fact alone brings up tons of problems.

First, the Great Crusade didn't start until M30 (the conquest of Luna being around 780.30M), so we don't really know how we could know about them so early if the Imperium wasn't even around. It could be a case like [[Hive Fleet Ouroboris]] and just have rumours or legends from the isolated human worlds about beings similar to the 'nids, and then imperial authorities just gave the hive fleet the same name as the menace from the old tales afterwards. If Colossus had been discovered by xenos first, there would be some sort of record of that in the hands of one of the biggest factions in the galaxy who would care (either the Necrons or the Eldar), because otherwise, no other superpower could've organized enough forces to destroy a full hive fleet and it would have devoured the entire sector.

Second, if the dating of Colossus's sighting is remotely true, that means a Hive Fleet has been going around a pretty big area of the galaxy and it has somehow not eaten enough planets to avoid being destroyed by the Imperium in M41 (we'll get to that later). We could say the Eldar could've campaigned against it, like they did with Hive Fleet Naga, but there are no records of something like that ever happening.

Lastly, if Colossus really did come in M28 and somehow stuck around until M41, how come no one said anything until Behemoth arrived? The Imperium of Man conquered the area during the Great Crusade, the Eldar were around before that, and other multiple minor xenos species were living there too, however none of them did anything to deal with Colossus. It couldn't have been dormant and hidden, because if it had, we wouldn't have those reports confirming its discovery in M28. Tyranid activity is not generally known for being subtle. Someone must have known and someone must have done something to avoid Hive Fleet Colossus's growth.

That's just the chronological problems. We have to get around other things as well.
