I've only just started the game, but I've done research. I know how you spawn bosses, and beat moon lord, but by a stroke of luck, at my third night I defeated eater of worlds, and found an unconcious man, who was a bar tender or something. I don't know what this is, as I've not heard anything about it, not even from my friends. It would be really peachy if someone could get some links to help me or even just state what's going on, because now I've got some weird bald guy in my house muttering something about a portal.

Thanks!
