My two cents on the Riven/yas killer theory
this is old as all hell but I wanted to give my thoughts on this theory So for those that live under a rock Yasuo's story is that he was an arrogent student who was the only in an entire generation to master the wind technique, he was put to task by his brother to defend an elder a humble task, he got cocky and went to fight in a battle that was raging nearby, winning it for Ionia but when he went back the Elder was dead he turned himself in but it was thought he was the killer, so yasuo fought his way out to find the real killer, on the way out he killed his brother but before he died he asked why he was thought to be the killer Yas's brother said he died to a wind technique so who else could it be. Riven was a soilder for Noxus, basically an uncle sam or uh an aunt.. idk that was a firm beliver in Noxian strength above all, but during the Ionian contact Singed used bio weapons on both noxian and ionians alike, Riven deserted.
So why is riven thought to be the killer? Well it simply Yasuo will comment on her broken wings (his Q is a knock up and so is hers, it also has a unique effect on the third hit) and the fact her ultimate ultimate is called wind-slash.
Well my thoughts are this
heres how i actually see how all charcters that could be potentially (or are) involved
innocent unintentionally framed
Innocent intended to be framed
Guilty Killer
might be killer (EXTREMLY unlikely)
Reasoning Lets go with the easies first yi and yasuo
Wuju could be some type of wind technique and if its not whos to say Yi doesnt know SOMETHING in it, however I doubt this for obvious reasons if the elder was a noxian cospirator yi killing him isnt entirely unreasonable but I doubt this is the case
Yasuo is innocent because his lore is from his perspective and he started drinking AFTER the incident so he cant be the killer
Heres were it get interesting atleast to me I Think Leblanc is the killer, however I belive she wanted to frame Riven, and was not aware of Yasuo's wind technique the reasoning I have for this is a few. 1. Leblanc is an assasin, only the elder died and there was no collateral damage if riven killed the elder I find it difficult she didnt also break something else, ranging from a minor vase breaking to a pillar collapsing Riven kit seems to suggest she is a rough fighter so no collateral damage is suspicious. 2Leblanc's motive could be considered simple, Riven deserted is a threat to noxus but not Ionia, give Ionia a reason to hunt her down. However I doubt Ionia knew Riven was capable of any sort of wind technique she was a captain and poster-girl of the Noxian military not someone hugely important however unluckly for yasuo he was stationed to guard that elder, and in fact I belive when yasuo left to fight the elder was already killed by leblanc using her mimic magic to copy Riven's wind slash heres how I think the scene went Yasuo is stationed to guard the elder Leblanc assasinated the elder with Riven's Wind slash yasuo remains unaware Yasuo goes out to fight he returns and sees that the elder is dead he turns himself in lore continues as normal
heres why I think this 1.Yasuo does NOT recognize that the elder was killed by a wind technique, and hes mastered it! so clearly it wasnt a wind technique, what if it was wind MAGIC made to look like a technique, yasuo has shown with his interactions with riven to know how to spot a wind technique yet is caught COMPLETELY off guard when his brother tells him the killer used a wind technique 2.If the Elder is discovered to die BEFORE yasuo "left" his word of going to fight could be execused as allibi building 3. when yasuo turns himself in he is immediantly accused so no other wind technique user was in the area OTHER then yasuo that ionia knows of 4.I feel like Riven would not kill an elder since they seem to be like spirutual leaders more then anything (Syndra's master and Karma seemed quite faithful) and shes not someone who kills anyone and everyone thats all tell me what you think
