As an aside the pub incident may prove useful to some of you who may be hesitant to start a narrative campaign.
By that I mean it can be very daunting to try and come up with a story with which to link your battles.
Just lay on your first game. Any pretext will do for that one. Boris the Slovenly covets Ragnar the Repugnant's Golden Stool for example.
Often, and this applies to solo, co-op and traditional gaming,you can forge a connection between events that happened during the game and run with them.
In the Battle of Naughty Rhyme there were two actually unconnected events that can be connected to give some back story to future games.
1. The Pub caught fire (random event).
2. The Wee Folk rolled over the 21st. without breaking a sweat. (luck of the dice).
Putting those two unrelated events together we now have a narrative: The Wee Folk, believing the pub fire to have been a deliberate act of orc barbarity, were berserk with rage and nothing could stand before them.
Now here is fodder for any number of future scenarios. If the rules being used cater for such one could say that the wee folk now "hate" the orcs, or that the orcs now "fear" the wee folk. Or to make it even for those so inclined the "hate" can be mutual.
In short, never let a coincidence go to waste when playing a narrative campaign!
