We think we know the history of the Earth, but there are secrets that lie beyond our ken and truths that threaten to undo our understanding of the universe. When renowned historian Alejandro Vela discovers one of these secrets—the ruins of an ancient and forgotten Aztec city—it sets into motion a plot that could unravel the very fabric of time itself. In The Forgotten Age Campaign Expansion, one to four investigators join an expedition to explore these ruins, venturing deep into perilous rainforests and forbidden caverns. Will they survive this dangerous journey? Or will it be their undoing? This expansion includes all of the scenario content originally featured in The Forgotten Age cycle, now repackaged in one box.
