Null Tokens (from The Room)

These tokens bear the symbols used in Fireproof Games' The Room series. In The Room, you must discover the secrets of a puzzling series of boxes left by an acquaintance; in The Room Two, the quest to open the boxes leads you into a whirlwind journey through time and space. The Room Three sees you trapped on an island with yet more puzzles to solve as you try and escape. The symbols represent the Null element, "between Earth and Fire, between Water and Air," that guides you throughout the games... but is it merely the final element, or is there something more sinister behind it?
