TL;DR
Summary pl0x.

You just took stories and mashed them together. For one, Almire was from somewhere else, not Cradle, over a thousand years ago. Over a thousand years, Owlite books and stuff would all be destroyed. Thus, the Owlites and Almirians were destroyed in drastically different time periods, not to mention location.

Margrel was not the leader of the Kat tribe. You have no evidence whatsoever for that fact. He was just some moron who killed everything accidentally.

Fer crying out loud...LICHENS CAME ON A METEOR. You haven't any proof that any other Slimes came on it save for the Lichens. AND IT'S ONLY THOUGHT THAT THEY CAME HERE THAT WAY.

Monomi is NOT a god in canon. It's the name of a Gun Puppy statue in the Haven Town Square.

You haven't proof that Vog is a great firey beast. For all you know he's a blob of water with a really bad sense of irony and humor.

It's not really logical to think that the Core, which had apparently no interaction with the Spiral Order save for the Alpha Squad (albeit allegedly), would randomly shoot a bunch of people to help it.

You don't know that the Owlites lost. They lost one battle, but they may have won all the others. Heck, that might be why Margrel opened the book, because they were losing.

right on for being creative dude, life is too short not to create something every day.

*Bwiiirrrrrrrr* Al mi ni keh bi bi ne ti mi noh? *Ka-chlick*

(Are you making fun of us?)

Right over... here.

Number one, this belongs in the Treasure Vault. Move it.

Number two, don't trust everything on the wiki. At least 4 pages had false info (Danger Mission lore).

Here you go. Don't worry, I charge very generous fines. Generous to my income, that is.

I'm pretty sure they were all separate canons, and may relate to one another VERY distantly.

I can understand Devilites and Undead mixing in, given that both Kats and Devilites have the ability to make summoning circles to call people in from other worlds.

Gremlins seem to be just...builders of Constructs. I mean, they seem to lack the real power and technological might to keep any other factions than themselves to rule. Heck, even their elite Crimson Order has in-fighting.

Beasts and Jellies...I'll say that MAYBE Lichens crashed onto the Wolvers' planet, or maybe they crashed into Cradle (which would explain why they're in Undead levels, Gremlin levels, and some Beast levels.) But I think it'd make more sense to say these two Monster families are segregated until they were added to Cradle.

Silkwings, I can assume from them being insects, breed quickly enough to spread to all kinds of stratum. This is why their origins are undetermined, and although they're classed as fiends, they're never mentioned in the actual in-game lore.

AND SIRIUS...

The being in the Core cannot be responsible for the crashing of the Skylark. If it could power up a cannon to shoot the Skylark from inside, then it would've been out of it's prison LONG ago, considering the amount of power that cannon had to shoot down the Skylark.

The infighting is most likely caused by Gremlin's territorial nature. They were designed to protect and maintain Cradle, so a few behavioural flaws could be tolerated if it meant they stoically defend the clockworks from all outsiders.

The enemy of my enemy is my friend. Gremlins are cunning enough to use other races to their advantage when combating knights.

Hex, let me. I have done extensive research on the gremlins. Gremlins are cunning creatures. They have developed machinery and weaponry beyond imagination. For instance, Seerus' deadly Grand Arsenal. Herex's chemical weapons. Even in the real world if these were used it would mean certain destruction. However, the gremlins can't succeed without one of the two methods: A coincidence happens and they take advantage, or gremlins use other races. Gremlin commonly use the method Aftermath Battle, meaning they would rather let other races take care of their enemies and they are done, or fight the greatly weakened enemy after a battle. One may think why gremlins could just team up with other races to form an alliance beyond imagination. However, we can see clearly that is not the case. Even though gremlins are smart and cunning, they can't form alliances. First, gremlin chatter is not understandable by other races, unless a gremlin knows Common speech, which is very rare. The Crimson Order members are exceptions to gremlin chatter. They can all speak Common. Second, gremlins can't form alliances due to the fact they are proud and arrogant. They would rather not rely on a race open-surface-ly. They would use other races secretly so the others won't know. Third, an alliance won't last long, due to the evidence that not even the Nine Crimson can't even control themselves and King Tinky is most likely a senile fool than a brilliant Architect long ago. After all, the Clockworks are old, so that means Tink is old too. Therefore the Crimson Order could be speaking for themselves now. The gremlins would make their enemy look as bad as possible so that other races would assume that is a race to be exterminated and then the gremlins would take their advantage. However, this doesn't seem like the best strategy, even though it is very effective. We can see that gremlin usages of other races doesn't always work. Usually other races find out. However, alas, there aren't many intelligent races now. Gremlins are perhaps the only race that is very smart and intelligent, other than the strangers and the Spiral Order. The strangers are too passive and the SO is too smart to be tricked by gremlin gizmos. We can see clearly now that gremlins don't use that tactic now. They prefer to make machinery in peace so one day they can destroy Haven. That still doesn't mean they use pure brute force though.....

So what you basically said in that large, unformatted block of text was pretty much I said just more elaborated (and patronizing to some)
By me mentioning that Gremlins are cunning, most people should be able to infer that the "the enemy of my enemy is my friend" line was referring to Gremlin's tactic of standing by (or passively assisting) while other non-negotiating species did all the hard work.

First, gremlin chatter is not understandable by other races, unless a gremlin knows Common speech, which is very rare

Extensive research you say? What about the fact that every single friendly Gremlin we've encountered can speak Isoran?

King Tinky is most likely a senile fool than a brilliant Architect long ago. After all, the Clockworks are old, so that means Tink is old too.

Here you're assuming that A: Tinkinzar is mortal, and B: Tinkinzar and The Architect are one and the same. Nowhere are these stated as fact.

Compared to Isorans, Gremlins aren't smart. They don't need to be: they make up for it in drive, and the advantage of being well learned in their environment.

I'm just gonna say that I really doubt that any of this lore stated by Sirius is true, since this hasn't been clearly stated within the game in itself, and the lack of any real stated link between certain monster families (Vog is really just some obscure thing, assumed to be an organism and have children. Monomi is nowhere near a god, just a named gun puppy statue) and so forth. The way how this THEORY is stated as a fact by the original poster just makes me wanna slap my face with a Rocket Hammer, since so many people seem to accept it as a fact and continue to build upon it as if it was really a fact.

It isn't. OOO doesn't state anything about this being true. The game hints at a lot of things, but ARE YOU GUYS KIDDING ME? You're really going to take a synthesized version of the lore and pass it off as a fact? *sigh*

Because none of this is true (except for the facts themselves, that Almire was a kingdom and Gremlins maintain Cradle and that Monomi was simply a named gun puppy statue in Haven and that the Kat Tribe had a great big conflict with the Owlites and that Fiends have summoning circles...), I cannot and will not accept that Strangers are "eternal in a sense, and are like recorders. They pass on information".

Even IF all your falsified lore WAS stated as true, it's a fallacy to say that since Gremlins and Kats do the same thing in their respective towns (Emberlight and Moorcroft).

Before we have any more discussion on this, can we all have a long hard look at the original post?

And Sirius, if you do want to continue with this, state this as your own lore. It just unnerves me when people try to synthesize hypotheses and pass them off as facts, especially since they haven't been proven.
