Ooh – sounds delicious! 

So we can get some nice dark paganism thrown in there then if it’s all Celtic-y! 

Also I’m assuming with the darkness and plague and poverty and what not that we can assume that the society is very divided – for example the hierarchy could be something like this:

King/Warlord 
King/Warlord’s immediate council & advisors
Noble warrior caste 
Warriors 
Peasants/Citizens/Mostly everyone else
Slaves & criminals.

Something like that right? Where we are the slavey criminally one? So no rights, no freedom, no nothing?
