I must be missing something.. I started the Rise of All Goblins Campaign, and traveled to what appeared to be the only available quest location on the map (the one that says "three weeks to start", represented by a castle on the map..) I took a week to buy equipment in Tamalir first..
My hero party lost the quest and the "campaign" was over... Is it really just a one-quest campaign? Or am I missing something (I hope so, and that seems the far more likely explanation). Duh!
