Diomin
Diomin is a dark fantasy role-playing game, designed by R. Hyrum Savage and published by OtherWorld Creations (OWC). The only familiar race in Diomin are the humans, who are divided into two cultures: the good-leaning "Tirasim" and the evil-leaning "Zeredites". Recently, OWC has announced plans to release Diomin material for the new version of RuneQuest, published by Mongoose Publishing.
