If you wan't a storyline but really can't think up one, just play the trilogy (Exile or Avernum). Jeff left many unanswered questions that I like to think where put there for future scenario makers. some examples are Lost Bahssikava (already being done), the Avernum territory in Vallorim, the second Slith Wars, Other Vahnatie tribes, the new and improved Tower of Magi, Who was Micah's successor, what came of Pythras's revenge, what happened to Athron's children, and many others.
