Regarding the new Varus lore and the future of the Darking

So with the new music vid and behind the scenes we pretty much got to know how Varus came to be and how he relates to the Darkin through the bow, thus solidifying the idea of the Darkin being trapped in some weapon only to be unleashed one way or another.

Out of 5, we have 3 confirmed Darkins in the game:

1. Aatrox: Where the holder was weaker than the Darkin (presumably in his darkin form after breaking free from the weapon and posessing the body I don't think it's his raw form since Riot is giving a unified theme of them being trapped to begin with).
2. Rhaast: A stable fonm where neither The Darkin nor the body is in full control, only getting unleashed through persuasion and specific battle pressure.
3. Varus: Where due to circumstances the darkin couldn't get total controll due to the strong bond between Val and Kai resulting in a new personality.

So where from here? What's next? Who's the other 2 Darkins? Do they already exist only waiting to be revealed? What would happen if all 5 Darkins met?

I wanted to take the opportunity to talk about Jax involvement with the Darkin and the possibility of him being one.

According to lore he belongs in Runeterra so he's pretty much without an origin, he had the figure/silhouette of Aatrox once is splash art which could possibly be a clue to his origins or at least his involvement with the Darkin. His personality is also unique, described as self styled and literately "the master at arms" which if you ask me reflects the aspect of war pretty nicely. He's also said to have a biting sarcasm which gives me the idea that whoever the darkin is or the body was they maybe shared a common mental goal aka the love of fighting and the use of sarcasm in battle.

Although there are quiet a few points which would debunk the whole idea of him being a Darkin ( or at least whatever idea Riot had may have been scraped due to the recent solidified changes in the appearance and key features in the Darkin).

1st off he isn't tied to any weapon. Now i'm not sure if it's said anywhere but as far as i know Darkins are tied to the weapon they possessed, although they being able to switch weapons would make 100% sense since they now have possessed another body thus breaking their ties with said weapon.

In his current splash art the figure/silhouette of Aatrox is taken nowhere to be found which could either mean that it was just a teaser for Aatrox (unlikely imo. since Riot haven't changed any splash arts once a teased champ was revealed later on) or the idea has been scraped so they decided to remove all leads. A third option would be that they just updated the splash art and didn't add Aatrox? Feels like a bit of a stretch but still possible.

2nd his physique doesn't match the Darkin theme. the purple normal looking skin doesn't fit the spiky red/grey build of the likes of Rhaast and Aatrox. Although who knows he might be a unique case similar to Varus.

Well that's all i have. What do you think? Anything i missed. I really enjoy the lore of this game although i haven't read through every single story there is so it's very possible i have missed sth. here and there.

I just wanted to make this thread to see what the community has to say, I'm legit curious ^^
