It's not fair for Rhaast to not have lore while Varus and Aatrox do.
Don't give us the excuse of Rhaast not being a champion.
Valmar and Kai are absolutely not champions yet they got their own lore alongside Varus. Without Rhaast, Kayn is nothing.
I do hope that in the next Darkin update, you guys give Rhaast some love and lore.
