Directly from Red Hook's Darkest Dungeon website: "Darkest Dungeon Presents is a comic series that tells the half-remembered horrors of each of the playable character classes in the game."
Made by Chris Bourassa and Trudi Castle, you can find the latest one here with links to the other three http://www.darkestdungeon.com/darkest-dungeon-presents-the-leper/
