It became standard practice in the groups I run with for the following to happen:
For my first PC to make an appearance as a quest giving NPC, usually as Lord of Orquacourt.
For Orquacourt to make an appearance. And inevitably be destroyed.
For the party to get a dragon-worshipping NPC ranger named Steve.
For one of Steve's innumerous brothers to appear as the BBGs mook.
For demonic help to arrive in the form of a homosexual balor lord named Fire Guy.
