The Game Master’s Notebook: The City of Ravenclaw: The Crossed Blades is a role playing game supplement published by Art of War Games. This is a five page PDF which is available for $1 from RPGNow. The PDF lacks bookmarks, but doesn’t really require them given its length. One page of the PDF is the cover and there are a handful of illustrations inside which are intended to represent some of the detailed NPCs.
Side Quests V: The Lair of Amzuulan the Sphinx is a role playing game supplement published by Art of War Games, part of the Side Quests series of short adventures, although this is one of the longer, and therefore more expensive, ones. The PDF is available for $2 from RPGNow and lacks bookmarks. This being a slightly longer PDF, bookmarks would have been nice, but they aren’t essential. The supplement is covered by the Open Game License.
Villains of the Week 1: Suffer, the Drow Evoker is a role playing game supplement published by Art of War Games. The supplement is available as a PDF from RPGNow for $0.50. It lacks bookmarks, but these really aren’t required for its length. The PDF is three pages long, of which one is the cover. The sole illustration is the one of the cover of a drow, presumably Suffer.
Side Quest I: The Mines of Tarifel is a role playing game supplement published by Art of War Games. The supplement is available as a PDF for $1.00 from RPGNow. It lacks bookmarks, but it’s short enough that they aren’t really needed. This is a five page PDF, of which one page is the colour cover and one page a black and white map of the mines themselves. The only illustration is that on the cover.
