Diomin is a dark fantasy role-playing game, designed by R. Hyrum Savage and published by OtherWorld Creations (OWC), publishers of the new edition of Chill. 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.
