The Iuz Border States Meta-Regional series of scenarios were provided for RPGA Network play (a precursor to Organized Play), and were distributed electronically on a limited basis to participating Dungeon Masters. While the scenarios are linked by geography and theme, they were not intended as a continuous "adventure path".
Because players used their own characters in Living Greyhawk, each of the scenarios supported a fairly wide range of character levels; this was accomplished by noting various adjustments the Dungeon Master could use "on the fly" to set the adventure at an appropriate difficulty depending on the actual characters engaged for the session.
Iuz Season Seven, played throughout 2007, took place in Common Year (CY) 597. Note that Meta-Regional scenarios were only legal for play within the actual geographic regions which belonged to the Meta-Region.
