I stole, shamelessly, the following table from Beedo. He designed it, as far as I can tell, off of the Rules Cyclopedia realms event table, altered for his Norsemen on a lonely isle Black City campaign. So I've taken some of the entries that make less sense for Goblin Wars! and rewritten them, as well as changing the description of many of the events I've picked. I've used it to generate future events to keep the PCs on their toes.
