(This is a teaching/practice campaign. I'll teach you to play the ORE (One Roll Engine) system Reign. And I will practice Play by Post roleplaying with you. And I get some DM practice. So Win-Win-Win situation.)
The war has ravaged the country, leaving nothing but burned earth and ruins in it's wake. Many survivors and fugitives are roaming the lands in search for a safe haven. But among the torn cities and the ruined lands there rise new dangers. Goblins and orcs claim the barren lands and attack all that pass, and bandits strip the corpses and living alike. There still are loyalist to the old king, hidden in far away areas and caves.
You are a varied lot, some came from your own volitons, others were found, and a few were forced. But it does not matter as your mentor Gerrik is teaching you the all he can. If you like it or not, you'll need what he can teach you to survive.
