Wow dude! That story realy sounds great! You're awesome and thanks much for writing!
The only problem about this would be that cities, built up by players, eventually would/should get destroyed or damaged when getting raided/captured by the followers of Morkam.
I also think a nice system for raiding towns could be, that people of each faction can suggest their king/leader to raid a city and the leader/king will ask an admin if that's alright and if yes, announce it in the forum with a date when the attack will start. So players of both sides can get prepared and well, I think it would be realy fun^^ I haven't got that much experience with the factions plugin yet so I don't know what is realy possible.
Realy, thanks for taking the time to write
