Returning into an Adventure I ran two weeks ago, I realized it could make for a published adventure. The adventures of an orc and his pals explores orc culture in ways people don't realize.
* Basic premise: This adventure only works if one of the players is an orc. Ran as a character development piece, the PCs journey to an orc village because the orc's father is sick. Also the orc's father's authority is challenged by Jubal the Ugly One because he has taken Dian the Beautiful -- the daughter of a powerful family. The PC must win back his father's honor and Dian by a blood challenge -- a fight to first blood.
When I ran the adventure, the players had a good time. Expanded into an adventure, it could be liked by orc lovers and those who play the Horde in the World of Warcraft MMORPG.
