*appears in flash of brimstone, angel dust and sooty robes* Sorry about that folks, my absence from the board today wasn't completely intentional BUT I got some R&R2 stuff I've REALLY been meaning to get at.
So anyway, to field the questions, what makes the Scarred Lands great, is this...BUT also the fact it's like any other D&D world. There's light, in the form of mighty paladins, the freedom fighters of Vesh, and the sundry of unhearlded heroes all fighting for their beliefs and gods, to the dark, the Penumbral Lords, wielders of mighty shadow magics, the Order of the Ancient, a cult of assasins, priests and wizards dedicated to Belsameth, the Slayer, the Lady of Madness, Magics, and Lycanthropes, plus the followers of Mormo, the Lady Titan of Serpents, Hags, and Witchcraft, proginator of the High Gorgons, ruthless human like creatures that have powers far beyond that of ordinary humans, and many others. To the Grey, the Sage Yugman, historian and recorder, a man with his own agendas, Virduk, perceived by some as ruthless and despotic, but still a man that lives by law and order and has made great strides in making civilizations in and around the wastelands of his Hegemony.
So I hope that helps explain why I think the Scarred Lands is popular.
And to your question, Maple, I would suggest you pick up the Divine and the Defeated, which answers your question quite well. But since I'm a generous man, I'll be brief. After the gods and titans aligned to defeat the Slacerians, there was a growing sense of discontentment among the gods, especially those fathered by Denev, who couldn't stand for the ravages of Garuak, the wanton slaughter and rape of Tanil at the hands of her father, Hrrinnurk, and the destruction of cities by Kadum, finally prompted the gods to join together. Belsameth, it's believed, just wanted to strike back at Mom, while Chardun had some similiar ideas. Vangal, though, it's believed joined in basically because the titans represented the best chance to show off his power and need for slaughter. As the eldest, senior, and most elemental of the gods, Vangal probably was getting bored slaying and leading small hordes of mortals against each other. What really set them all together was the fact Enkili, after playing a rather cruel prank on Mesmo, had his divinity STRIPPED from him/her. That pretty much sealed the deal, as NONE of the gods wanted to lose their power. Again the Divine and the Defeated explains this a little more clearly, BUT that's the gist of it, Maple.
