How do you get the Demacia Icon?
It was a mission or event reward. Riot's description in the client reads: “Earned by participating in the Demacia lore update on the League Universe site during 2017 or completing missions during the release of the Runeterra map.”
Is the Demacia Icon still available?
No. Riot tied the Demacia Icon to 2017 (mission reward), and it does not normally bring back past event rewards or bundles.
