So I just found out there’s a threat going around about people that are looking to harm Homestuck cosplayers at cons, even kill them. To the point certain conventions are hiring more security according to a reliable source. So please guys, if you’re a Homestuck cosplayer at conventions try to stay in a group. Be safe. I don’t know where all the threat is, but it is being taken seriously enough to hire more security at my con.
