I have acquired LOTS of alternate source material from The Net, related to Black Kingdoms stuff ...
I downloaded most of it from hyboria.xoth.net and the other 'common' Conan/ REH sites. This has given Me a rough compilation of background source material that pretty much covers all of the topmost Black Kingdoms States, as well as the mixed Southern section. I have a lovely detailed map containing sub-areas of Hush, from the Styx down to Amazonia (!). I like MAPS, and I'm pleased to see detailed expansions within each new Mongoose module/expansion. I usually upgrade the map up to a larger size, recolour it, laminate and mount it on hard card for My Players to see during a game.
So far my "research file" contains : Kush map, The Lost Magic of Hyboria by Ric K. Rodriguez (thankx Eric)(this has the 'Spear of Ajujo' and 'The Claw of Onn'Rar' within ...), Raven Blackwell's "Dekerta's Laughter" Spell (from Raven's Sorcery excellent contributions), REHs Conan Continental Maps (article) listing on The Southern Continent, The Lands of Stygia and Beyond, by Dale Ripke, and several useful artticles, Conan NPC,s and items of suitable interest related to the "X-cities" and artifacts (green fire stones), Lotus,etc.
I am facinated by the proximity of the native locations and the ancient Xuthal/ Xochotl. Shades of "Red Nails", etc.
Anyone made any other Discoveries or useful background source material for cooking up Scenarios ? I loved Tales of the Black Kingdoms, and look forward to getting some of the new text additions (So far I've only got Aquilonia - but I'm drooling for Stygia ...)
PS: I'm thinking of trying to write a high-level Conan ruin/ underground city module based upon the discovery of Python, the ancient Stygian fabled city ... (Unless Vincent has already beaten Me to it within the Stygia sourcebook ?).
