Version A is intended as a first insert for this game (Aeon's End or Aeon's End: War Eternal). Version A, in addition to the card and gate trays, includes two token trays that can hold the tokens of two base games (Aeon's End or Aeon's End: War Eternal) and four expansions (Depths, Nameless, Void, Outer Dark). All heroes and Nemesis cards from the aforementioned base games and expansions will also fit into this version. The containers for tokens are slided - nothing will fall out when the box is stored vertically.
Version B is intended as a second insert for the other base game (Aeon's End or Aeon's End: War Eternal). It complements the space needed to store cards. It includes an additional gate tray and one of the card trays is a card holder.
