Narrative Content for Game Design only had seven students in it, and all seven of us collaborated on an idea I pitched, a sword-and-sorcery setting called Wilderlands. Each other student designed a region and its indigenous culture. I wrote an outline for a hypothetical RPG set in the world, and edited the other student's work to ensure narrative consistency.

During your travels, you would encounter terrifying beasts and bizarre cultures, all warped by the strange magic coming from beneath the lake at the heart of the Wilderlands. Your decisions would affect the life and death of your caravan, and whether the survivors became peaceful nomads, or savage marauders, and could lead to a horrifying revelation about the City you left behind...
