GDQ1-7: Queen of the Spiders
Queen of the Spiders is the super-omnibus format for the Advanced Dungeons & Dragons 1st edition Adventure Path, spanning a set of seven individual adventures that collectively make up a mega-campaign; Against the Giants, the Drow Trilogy, and Queen of the Demonweb Pits.
There's a new prologue. First, there's the lead-in from Scourge of the Slavelords, where the surviving slavers are gaslighting the PCs. This part is artificial and contrived. Then there's an overview of giant-occupied Sterich. This bit is... pretty good. Carl Sargent's 2e From the Ashes Greyhawk revamp uses that for its Sterich.
