User summary:
The Onnwal 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. Season Five, 2005, included four scenarios, all set in Onnwal in the Living Greyhawk campaign. While the scenarios are linked by geography and theme, most 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.
