The most I've gathered is that there are 5 Darkin. Aatrox seemingly the Darkin of Rage, Rhaast the Darkin of Destruction, and Varus the Darkin of Vengeance. So if I'm correct (which I may or may not be) each Darkin is the embodiment of some kind of aggressive behavior that always causes pain and suffering to the people of Rune-Terra. So is it possible there is a Darkin of Hatred and a Darkin of Terror or something like that?
The darkins are a physical species,they don't really embody anything.
However Rhaast does refer to Aatrox as war and himself as death,which leads to some people assuming that the darkins are gonna represent the 4 horsemen of the apocalypse(as the horseman with a sword was war and the one with a scythe was death). This would likely make Varus pestilence or conquest(pestilence seems more likely with abilities like blighted quiver),which in turn would likely mean that the last 2 darkin are famine and conquest.
From how the lore is going the Darkin aren’t really embodiments, that what the Demons are. Tahm and Evelynn represent specific foibles of mankind. The Darkin may vaguely resemble the horsemen (we do more or less have War, Death, and Pestilence so far) but we don’t really know how intentional that is
Well the community is trying to prove the 5 horsemen of the apocalypse. So far we have Aatrox as war, Rhaast as death and Varus as pestilence/conquest (not sure which one).
About your theory: Aatrox is not really shown to be in rage; Destruction is not really a behavior but more of the consequences of the said behavior. The other thing is that we shouldn't give the Darkin such descriptions. This way we are underestimating them: group of demons who don't think about anything but one thing. They are more complicated from that as we see Rhaast roasting Kayn and being sarcastic. Plus that when Rhaast wins the battle he says "Poor Kayn. All this plans for nought". I think that this is the only moment when Rhaast really feels sad about Kayn (not as he wants him back but more like acceptance of Kayn's death). What am I trying to prove is that a Darkin of destruction would never talk this way. Rhaast seems to be patient as he never tells Kayn anything about anything. They are talking just like friends but a omen of destruction could never talk to someone on that level. The last thing is that vengence is not always a bad thing. You have Kalista and I like her idea but she somehow is not particularly bad or evil. Vengence and rgae is what won the war for Throy. If Achilles didn't fell into rage and didn't want vengence Throy could have won easily. The rage of Achilles didn't really damage the greek but actually won them the war and killed the leader of Throy's army.
Aatrox is rage? have you ever played Aatrox bro? Have you listened to his VO? He's the most stoic and composed champion in League of Legends. If he were to be impaled by thousand men he'd smile out of pride in them, then splatter their insides in a grand oers d'heuvre. Aatrox is War
in the case of 4 horsemen if they were rhaast is death Aatrox is war and varus is famine(it makes way more sense then pestilence like for example he hungers for revenge maybe) i dont know where you guys get conquest when that is just a subcategory of war and even then they don't represent anything there names just mean things Aatrox is fierce and Rhaast is obey(he literally says it to Kayn in game when he asks what does Rhaast mean). The only one i don't get is Varus his name means bent outwards no clue as to why(maybe the bow)
