Grave Matters - Dig Deeper is a 30 pages booklet full of new material for your Mörk Borg games, all with a common skeletal theme. Grave Matters is not a stand-alone game and a copy of Mörk Borg is required to use it. Grave Matters - Dig Deeper works better if combined with the first Grave Matters booklet, but it's not mandatory and can be used without it. Grave Matters is an independent production by Rinaldo Agostini and is not affiliated with Ockult Örtmästare Games or Stockholm Kartell. It is published under the MÖRK BORG Third Party License. MÖRK BORG is copyright Ockult Örtmästare Games and Stockholm Kartell.
