From the description of Fury in the Wastelands: The Orcs of Tellene on Amazon, it looks like this is quite an important part of the campaign setting:
Fury in the Wastelands: The Orcs of Tellene at Amazon.com wrote:Fury in the Wastelands: The Orcs of Tellene (Dungeons & Dragons: Kingdoms of Kalamar Sourcebook) Paperback – May, 2002
by Paul Wade-Williams
The definitive orc sourcebook for Dungeons & Dragons and the Kingdoms of Kalamar, designed for both the player and the dungeonmaster. Includes five orc sub-breeds, new orc-related skills, orc spells, new orc weapons, six orc prestige classes, feats for orc PCs and NPCs, orc magic items, orc alchemical mixtures. Also includes discussion of the orc society and religious beliefs. Three complete adventures dealing with orcs.
What is the setup for this orc society?
Does this work like a Kingdoms of Kalamar sub-setting (with it's own map) or are these socieities scattered in among other races?
Kenzer & Co kind of pitch these books (like a lot of 3rd Edition third party publishers) as if they are useful to people who are not using their campaign setting. How well does the religion swap-out (or swap-in) for the religion in the core 3e rulebooks? Could the two religions be used alongside each other?
Is this a book for NPCs or are PC orcs a big part of Kingdoms of Kalamar?
Are the orcs "bad orc" like in Green Races, or is there a variety of alignments (like with humans)? Would the included adventures work with Green Races?
Are there any other books (KoK or not) that would support The Orcs of Tellene well?
