From the introduction:
Frontier Justice is a four-hour game for six Oruskan player characters in Desolation, the post-apocalyptic fantasy roleplaying game. The playable Oruskan races include kobolds, goblins and orcs.
In this adventure, expected supplies have not arrived and the orc chief of the Burning Shoulder tribe is angry. He has sent a group made up of orcs, goblins and kobolds to bring back the supplies or find out what happened to them. During this adventure, players will have a chance to view the world from an Oruskan’s point of view and discover that they aren’t the only monsters in the northern wilderness. Combat, investigation, diplomacy, and tough decisions await the player.
