From publisher blurb:
Herein you will find the Incompleat Talamhur -- two INCOMPLETE volumes of lore and rules for the World of Talamhur and the Land of Carregdubh, as well as two maps, one the 25 mile-per-hex map of Aentyr -- the region once ruled by the Tuatha De Danann, the other Carregdubh, Region 01 of the 25 Regions of Aentyr.
Volume one is the Incompleat Talamhur -- Carregdubh, Land of Black Stones. Originally designed to be a series of 25 booklets, the "Chronicles of Talamhur," the first one is incomplete, detailing portions of Carregdubh. Some areas are described in complete detail, others are skeletal, and still others merely have a hex number and a name.
The other volume is the Aentyr Cyclopedia, which was to include details on the races, pantheons, and other "high-level" information for the entirety of the 25 Regional maps. Also, again, incomplete.
