OK, here's my ideas about what's going to happen with Parson, etc...

1) Parson wins the battle of Gobwin Knob (of course).

2) Parson somehow gets sent back to the 'real' world and has to deal with the shock of going from no-name-smuck to chief-warlord to no-name-smuck again.

3) Parson gets called back to Erfworld, but this time by Ansom and company (so even though he's recognized as a good warlord, everyone on "his" side still hates/disrespects him.

4) Some of Parson's friends or net-nemisises get called into Erfworld too, and he has to match wits against an opponent who is his peer/superior in battle.
