Pretty much he's a guy from the Video Game called Dark Souls. It's really hard. Solaire is a nice guy who can help you out on some boss fights and a pretty chill Dood. He also says a lot of memes spawned from him, like Praise the Sun and what not. If its a meme from Dark Souls, chances are its from him. Dark Souls 2 came out not too long ago and there are still hints from him, so everyone is bringing him back.
