Darkin lore theory
If we look at Aatrox, he's a demonic looking being with a "Living Sword" that thirsts for blood and can heavily influence others, increasing bloodlust or inflicting them with fear and doubt. He is also able to "corrupt" people as seen with Tryndamere (shown more in his Demonblade skin) and has something to do with Jax (he can be seen in the background of Jax's splash)
The particularly interesting thing to me is the Living Sword bit and the ability to corrupt. Perhaps Darkin are not what they seem to be.
What if the Darkin themselves are weapons?
Aatrox- the Darkin Blade
there are a few hints towards this, in Aatrox's case:
-His sword needs blood, when it drinks blood his powers increase
-His large blade is seemingly weightless and "hypnotic"
-Aatrox has been around for a VERY long time.
-His body and blade move in unison as if one being" - quote from lore
I believe the SWORD that Aatrox uses is Aatrox himself, the body does not matter. The blade could hypnotize unsuspecting people and possess them when they grab it, transforming their bodies to look like Aatrox does now, maybe to establish an appearance.
It is said that there are 5 total Darkin remaining, with only 3 known to history, yet only Aatrox is ever mentioned. Perhaps there are Darkin hidden in the League's ranks this very second.
If my living weapon theory is true lets look for other that fit the bill, mainly being a powerful item with a corrupting nature that possesses the host. I can only think of two others. Brand and Varus.
Brand, the Burning Vengeance.
He is presumably a spirit or demon that possessed the body of a man named Kegan, transforming him into the Brand we know today.
Brand could EASILY be considered a living weapon (hi Aatrox) as he conjures fire and flame and his very body is molten.
lets compare brand and Aatrox.
-both desire destruction and violence
-both are technically two beings in one
-both have been alive for an extremely long time with a very mysterious backstory
-if my possession/corruption theory for Aatrox is correct, both corrupt normal people to obtain new bodies (Kegan was hypnotized by the flames as Aatrox's sword is said to be hypnotic as well)
"This body is but one of many" - Brand.
Varus, the Arrow of Retribution.
Varus was a normal archer when his village came under attack from noxian soldiers. His village was losing terribly while he was guarding a Corruption (there it is again) and performing his duty as a guardian. His village and family were slaughtered and the noxians were heading his was, and in order to defend the corruption he took it within himself.
His body undertook a transformation, corrupting his arms and legs and feeling "malevolent energy" bond to him and becoming filled with hatred.
The corruption he absorbed could have been the energy or spirit of a Darkin, similar how Brand was just a flame when Kegan found him.
now lets compare to Brand and Aatrox.
-all desire destruction and violence (aimed towards the noxians for Varus)
-if my corruption and living weapon theories are correct, they have all been corrupted and changed in some way
It's true varus had less to go on but he has the shortest lore of the three
I find it really interesting that I could find 3 to fit this living weapon bill and theres 2 more "unknown" to HISTORY, perhaps meaning there are 2 Darkin in the making, but who? Tryndamere and Jax.
Tryndamere is already regarded as Aatrox's "greatest creation", he already desires the destruction of Aatrox, and, in his Demonblade skin, we can see He's fused with his weapon, similar how to the others I've mentioned are fused to something and is the only person known to have survived a direct battle with Aatrox (lore wise)
Jax is already the perfect killing machine, able to best the mightiest foes with nothing but a lamppost, and with the appearance of Aatrox in the background of Jax's splash art could show that Aatrox is watching Jax, perhaps even training him, and waiting or perhaps thinking of a way to turn him into a Darkin.
Another little fun fact, all of these people have glowing eyes, except maybe Jax because we cant see his face (Tryndamere does in ult with Demonblade skin as seen in the video Riot made)
And there it is, the three current Darkin and the 2 not yet known to history.
What do you think, could the Darkin really be weapons or am I just making stuff up?
and likely
all have the ability to completely posess and control a living being(sure its a plant in maos case,but humans in the cases of pantheon and tahm kench),while also having full access to their powers.
By that logic any of them could be a darkin even though we know they aren't ones.
