Sir Xaris, building on his namesake character from last year's postfest, the paladin Sir Xaris the Unabashed, Proclaimer of Truth, Defender of Right, Bane of the Wicked.
Sir Xaris writes: "Ever needed a higher level base of operations for your characters than the Keep on the Borderlands? Welcome to Sanctigaard, Eastboro, and the Demesne of Sir Xaris! If your campaign is pre-Greyhawk Wars, your heroes can use this village as a base from which to make assaults upon the humanoids and other mysteries of the Pomarj. If you wish to incorporate the Greyhawk Wars into your campaign, Castle Sanctigaard is a great place for your characters to make their last stand in an Alamo-like finish. If you simply need a new and exciting NPC benefactor for your PCs, this is the place."
When Sir Xaris says high level base of operations he isn't kidding (Sir Xaris' warhorse Gonfalon is mighty in his own right). Give this postfest article a look, because it follows through on all the promises in the blurb and more.
