[Champion Concept] Rapha, The Shadow of Demacia

I wanted to try and make a Demacian champion that isn't heroic and works in the shadows. This is my attempt.

Name: Rapha, The Shadow of Demacia Lane: Mid/Top Role: Assassin Resource: Mana

Lore: Demacia is known as the home of the righteous and just. A shining example of honor to all of Runeterra, but the brighter the light, the deeper it's shadow. Rapha is the leader of the Demacian Shadow, a secret organization founded to research dark magic, monitor Demacia, and execute assassination missions. Secret even from the Dauntless Vanguard, Demacian Shadow aided in their every battle by weakening the enemy forces before the conflict. While some within the organization speculate about Rapha's unholy dealings, none can argue with his results.

"Some wars are won with battles, most wars are won with one knife placed artfully from the darkness." -- Rapha, speaking with Garen about the intricacies of war.
