This is a cursed entity that was not a living carnivorous tree in the past, through a ritual to summon god himself he was granted a single wish of his choosing, he chose to be immortal but what he didn't expect was him being turned into a tree with no other option than to steal other human's lives by sucking their souls out of their bodies using his tentacle spikes on the top of his tree body as displayed in the picture above. It has now been more than 500 years he has been living as a tree, he has forgotten his name and his past, all he remembers is his objective to survive and kill in order to extend his life. 

His eye has an entrancing and attracting glow to it, when you set your eyes onto that glow you have to get close to touch it and before you know what's happening it's too late and he is already consuming your soul, how he lost his other glowing eye is a story lost to time.
