Aeon's End is, well, coming to an end. And as with all of us, it ends with the grave, so to speak. Legacy of Gravehold is the new expansion for the game that's up on Kickstarter now. Bigger than other sets, it will finish out the narrative of the game, leaving with a climactic finish.
From the campaign:
The campaign's more than 6x funded with 15 days to go.
