Hmm, just one thing, if Herex once belonged to Crimson order, then why did he write 'nine are blind' in the recon module? It should clearly be 'eight are blind instead', or was he replaced by someone else that we don't know? Or is the nine members of the crimson order something else completely.

And now, what is the iron law? And who broke it? Serrus? Tinkinzar, or someone we have yet to seen.

ps. I am rather dissapointed with how Herex looked... I always imagined him as a educated looking, glasses wearing scientist with an eccentric mad man beneath his white lab coat. but oh well, it is OOO afterall.

Midnight-Dj- I personally believe that a scientist look doesn't fit with Herex because as the note says ' He sees everything in the dark' which is something that a ninja would be most likely to say.

Colray- I saw that scenario room once and from the looks of it it seems that someone is killing the gremlins,maybe It's Herex since in the updated missions Spark and Roar you can see in the last depth of the mission you can see black squares floating around the room which they sort of look like the ones in the shadow lair.
This means that Herex as found a way to open the Core using the artifact, also he knows about the dark monsters which the module 'to the core' describes,but then again this makes me wonder what type of living creature is inside the core since in Mission 'Spark and Roar' it says :The nine are deaf, they cannot hear the Resonance that beats below within this world' so it means that the core could be something which is alive or an egg which grants power.

When the note says
The Iron Law is Broken!
The Crimson Order is False!
The nine are blind, they cannot see the Truth that lies below.
The nine are deaf, they cannot hear the Resonance that beats below within this world.

I believe it says that the members of the 9 are corrupted and they each want the power to themselves.

But I fell that there is need for more information needed before starting to create a timeline because we still don't know almost anything about the other Members of the 9 also of the King of gremlins and the artifact.

You think of that but then you don't think of ninja? Ninjas always use poisoned weapons

a quick search of the wiki will reveal that:

-he is also called "the whispering venom"
-he has at some-point been a member of the crimson order
-he is "no mere gremlin" ( this maybe taken literally or figuratively as not much of Herex is ever seen)
-he owns compound 42, a bioweapons facility
-he is capable of sending a group known as "iron assassins", a formidable force who may be behind the scenario room attack as mentioned in other posts
-his relationship with seerus may be deteriorating as seerus presumes the iron assassins have been sent to kill him
-razwog works along side Herex
-he may have a relationship with the swarm
-he continues to fund the development of weapons

MY CONCLUSIONS:
-Herex is a member of the crimson order who uses the power that gives to fund extensive weapon research.
-Though still one of the nine, Herex has become distant from the other crimson order members and so resorts to scheming without their knowing
-Herex uses his arsenal of weapons and research to arm his own group, the iron assassins. this technology allows him to cloak himself, and stage the heist on the lab.
-Herex acts without the knowledge of the nine. he ensures this by covering his tracks at any cost

P.S. - Herex may or may not be male i just chose to think of him as male.

I do believe that "iron assassins" is Gremlin designation for knights. After all, knights typically work in small groups, and usually seen carrying on some sort of mission, which sometimes involves killing a renowned being. And remember that only Emberlight gremlins know something about the knights, so unless Crimson Order has spies in Emberlight, their vision of Spiral Order would be quite one-sided.

Otherwise, yes, Herex has gone rogue long ago. My crazy idea is that he might have striken a deal with the Swarm - if Swarm is sentient enough for that - to open the Core using the artefact and let the Swarm devour the entity inside.
