Let's pick this up right from where we left off yesterday from here. Then we've brought Luz into the equation of Greyhawk's worsening situation yesterday. And here's where events get interesting & the situation within the Borderlands. James M. Ward's Advanced Dungeons & Dragons Greyhawk Adventures changed everything within the Greyhawk campaign setting. Why?! Because it was the transition book between Advanced Dungeons & Dragon first edition & second edition.
Of course there is & this is where our PC's come in! Greyhawk maybe a great Sword & Sorcery settting gritty as it gets but it's also a place of divine power! Greyhawk sport's wizards such as Bigby, Mordenkainen, Nystul, Tenser, and Rary As well as dieties both major & minor with all concentrations going onto the PC's heads. The history of the Borderlands within a Greyhawk campaign is tied directly into the history of Hommlet & the temple of elemental evil. Here's that history from from the Greyhawk wiki entry;"In 566 CY, forces of evil from Dyvers or the Wild Coast constructed a small chapel outside the nearby village of Nulb. The chapel was quickly built into a stone temple from which bandits and evil humanoids began to operate with increasing frequency.
In 569 CY, a combined force was sent to destroy the Temple and put an end to the marauding. The army included regular forces from the human kingdoms of Furyondy and Veluna, dwarves from the Lortmil Mountains, gnomes from the Kron Hills, and elven archers and spearmen."
" The site itself remained, however, and over the following decade rumors of evil presence there persisted. The Viscount of Verbobonc and the Archcleric of Veluna became increasingly concerned, and cooperated to build a small castle outside the Village of Hommlet to guard against the possibility of the Temple rising again."
Hommlet is outside of ACK's Borderlands region itself & it's one of the key areas!
There is an update of the events at the keep within Greyhawk Adventures as well!
