After creating magic to breathe underwater, Gygar leads a team of mages to explore the sunken ruins of Gravehold. There, he discovers an abandoned girl who has learned to fend for herself, and a familiar face who has come to terms with his own darkness. But humans are not the only ones lurking in this subterranean city.

Go back to Gravehold is an expansion for the cooperative deck building game Aeons End. This expansion has two mages, two nemeses, and several new player cards and treasures.
