check the "Crimson Monolith" in the updated Darksun Boxed set. During certain moon phases Tarar'ri step out, check out the area then return.
But besides that...this is MY version as I stated in past OOC comments. I let certain things slide to fit my world view and to make it a more "user freindly" campaign world. There is metal on Athas but when it's 140 degrees do you want to wear it? Have it reflecting sunlight in the desert?
Besides that, I would think the fiendish would want to be here more since there are no conventional gods here to slow them down or stop them. No paladins means more fun
If I include anything else that dosn't fit (and I promise I will) I'll try to do an OCC note on it.
Currently I know where Mania is headed until roughly 20th level (now 1/2 way through 5th) and there will be MANY non-official inclusions seen.
Without giving up much, expect Avangions, Dragon-kings, Pyreen and other power players to become involved along with a ....ah that would be telling.
Thankyou for reading. Keep up the comments. I like to hear from everyone, whether it is accalades, critiques or questions.
