Talk:Yasuo/Background/@comment-4573373-20131124074657

So...... Yasuo and Riven clearly know each other. Yasuo has a special taunt against her. Their Q's are INCREDIBLY similar. They also use wind in some way. I am assuming that, before Noxus attacked Ionia, Yasuo and Riven trained in the same sword school. Then, after Riven and Yasuo graduated, Noxus invaded Ionia, and Riven killed the elder. This is just a hypothesis, but it makes too much sense.
