This sounds embarrassing but... How do I add cogs? What is this ghost thing they speak of? All I wanna do is add fog for cryin' out loud!

Could someone explain in detail on how to add a ghost-what's-it-called?

Ok, a the ghost the cog is refering to is the location in which the fog will be produced. It is basically looking for a thing to target. The reason they call it a ghost, is because the ideal thing to create this from is the "ghost" template. Simply create a new thing, set it to ghost, and then put the thing number in the cog.

Those who stare in the eyes of death and laugh will be the first to go.

*Whew* Thanks man.
