Hi,
I'm one of the plot members for SoMi. One of Three.
A typical event starts around 10 at night at one of three (well two this year) campsites and lasts until the players are exhausted on Saturday or some days early Sunday.
Each camp represents a different city that adventurers visit.
We as a plot team have a super focus on player proactivity and have created a large world to play in. The world is your oyster here, so any kind of story you're interested in, it's very easy to get involved in.
In regards to the world.
The game is set in the Kingdom of Dragonreach. A fledgling kingdom that just fought against unspeakable odds to reestablish itself.
Adventuring takes places in two cities Azyl a city far to the south near mysterious mist that is rumored to take those who walk through it to another world, and Valbrough a former trade outpost next to the old capitol city.
As Joe mentioned if you have some specific questions, feel free to ask.
