Rifts Worldbook 10: Juicer Uprising (1996)
Zack: As seen on a brochure at the Coalition tourism bureau.
Steve: This guy made fun of our skulls. Will you?Zack: Good thing they have the Coalition skull symbol on their skull masks or I might have mistaken them for someone else wearing all black skull armor.
Steve: You joke, but mistaking skull factions is a real concern for people in the Rifts world. It can lead to some really embarrassing mix-ups.
