Where's the best place for finding information on Footfall? My players seem quite interested in the activities at Footfall, so I've been trying to gather up as much information about it as I can.
So far I've found the Eye of the Needle which starts in Footfall with the 7 Witches. I've also found out about the Kasbillica Mission in the Vaults of the Forgotten in the Edge of the Abyss
Where else can I look for more information on Footfall? I'd just like to draw upon existing literature as much as possible before I start inventing factions and things.
