Clash of Worlds
Versatile Session Roster
Instead of each game session always requiring the same players and following an epic story arc, the campaign will revolve around 5 loci of adventure. Each player will have a character on or near one such locus, and the game session will follow the story arc that involves the players who attend.
What this means is that if John and Biff and Steve and Mary all start an adventure and are deep within the Underdark; it will only continue if all and only those players show up for the session.
If the group of players changes then another locus will be activated and we will begin a separate adventure.
If for instance you would like to bring a friend to the campaign, but they have limited experience or uncertain interest we will do a Monster of the Week episode using characters in another area from that of the Underdark spelunkers.
If Steve on the other hand is unavailable for some time, and the rest of the group would like to get back to some story arc sessions then another group may take up the banner to search for the lost adventurers or perhaps pursue some other goal.
In this way the campaign continues and the actions of players can still affect the outcome of the larger story arc.
