[Champion Concept] Arkinah, The Demon Tree

It is a failed experiment when scientists used parts of Maokai, demonic blood and voidspawns to create superior self-healing bio-armor. Viktor was the lead scientists in this project, but decided to leave it, because it didn't interest him anymore. However, as a by product the demon tree was born. This demon tree is nothing like Runeterra have seen before. He devours, consumes and absorbs every living being or any thing with magic power. Demacian army managed to stop this creature from devouring whole world and broth it to institute of war. What happens next only the time will tell.
