I have been through the forum and the rule book and I cannot find a graphic that corresponds to the neutral(s) that are to be placed in the tile.
Dragon Head, Beast man, also what neutral is supposed to go in the tile that has that thing that looks like a comet?

You will find the corresponding icons on the sheet with the neutral's stats and special abilities.

Ok, I am offically losing my mind, where is the sheet that has the neutral states and special abilites?

I know, turn the sheet over.
