User blog comment:Krauserlols/Is Riven a real Wind Master?/@comment-10958553-20131217060627

CRAZY THEORY: Yasuo is the only one in his generation to master the wind technique.

The Old master was a wind master if I am correct? He was killed by a wind technique was he not?

My theory was that the master killed himself.

REASONS: Senpuko (Is that how it's spelled?) is a japanese tradition (Ionia is basically the asia of runeterra) where you kill yourself, often to regain honor. He possibly sees himself as a failior for teaching Yasuo.

Comanders of all nations have ,on occation, commited suicide to prevent information from falling into enemy hands. It is possible he ended himself to prevent his secrets from falling into noxian hands. Possibly after a battle with Riven that ended with him helpless (except for his suicide)
