Yeah. Titans. They're dumb, stupid, but they eat people. Just for the hell of it. They're as tall as three people sometimes and naked, but they just go around eating people and shit. They were monsters in my world and I was part of a military team that trained to fight and kill 'em.
Oh. Gotcha. Cause, I know iron is good for hunting ghosts. Dean taught me that one! Sometimes demons. So, yeah. Ain't there some other magic you can do to counter iron being bad for you?
