A simple low-fantasy game, going through common fantasy-genre tropes.

Backdrop: War has been going on for generations. The glory of the old empire is all but lost. You are special and destined for greatness.

Plot: Join a west-bound caravan to lands unexplored since the empire's demise. Discover forgotten secrets and get rich and powerful on the way.

Not sure about game system. Something like low-level D&D with nerfed magic and grittier combat. If this sounds interesting to you, you're welcome to suggest one.

You are also welcome to suggest fantasy tropes you'd like have included (if they are appropriate to what is sketched above).
