You know guys I have doubts that Riven was the one who killed the Ionian elder.

In her lore, it states that the blade was "forged from runes and imbued with Noxian spells." So, Wind Slash came from that and not because Riven is a wind technique practicioner. Besides, she stayed in Noxus since childhood.

They're portrayed as enemies/rivals cause probably they met in the front lines when Yasuo left his position.
