Exactly what it says on the tin.
I have been playing League since last August, and I have mainly played 
(Nasus) since last September.
Recently, I watched one of my friends play as Nasus, and they had "Riot K-9" Nasus. When I got some RP, that was the first skin I looked for, but it wasn't available. How do I get this skin?

Even the codes don't work anymore. Asked Riot Support about his return on Twitter last week and they said they were unsure :/
