Sweden. They brought us ABBA, but they also brought us Amon Amarth and Meshuggah (all bands listed here are favorites). We also got Blue Swede, but that's as it may be. What I'm saying is that things can get dark over there. That shows in their music and also in their RPGs. If you're looking for the darkest of the dark fantasy settings, you might want to check out Mork Borg, now available from Free League Publishing.
From the website:
A doom metal album of a game. A spiked flail to the face. Rules light, heavy everything else. Today, artpunk roleplaying game MÖRK BORG was officially released by Free League Publishing. Designed by Ockult Örtmästare Games and Stockholm Kartell, MÖRK BORG is the first RPG to be published under Free League Workshop, Free League Publishing's sublabel for selected externally developed games.
MÖRK BORG is a pitch-black apocalyptic fantasy RPG about lost souls and fools seeking redemption, forgiveness or the last remaining riches in a bleak and decaying world. Who are you? The tomb-robber with silver glittering between cracked fingernails? The mystic who would bend the world’s heart away from it’s inevitable end? The world is dying. And you with it.
