Rumbling

A row of titans will appear across the outer layer of a random side of the board. They will roll a D6 to see how many tiles they march forward. If they touch a tile, all characters, minions, items, and components in that tile are instantly removed from the game. When they reach the other side of the board, they rotate to the next side and immediately march again. 7 titans march at once, which gives you a chance to avoid their wrath.
