Editing Ghostwalk (section)

===Non-Human Nations===
*'''Coil''': Everything is snakes. The sky, the ground, the trees, the air itself... Okay, not really, but there are snakes everywhere. It is a demiplane roughly 50 miles long and 30 miles wide, surrounded by a wall of petrified snakes. Snakes grow out of the ground, swim in the lake, and form a mighty river. Every living creature on Coil is either a snake or a snake-like abomination, and the [[yuan-ti]]<sup>TM</sup> live in cities of stone that writhe like snakes. At their heart is Tragaash Daur, a yuan-ti cleric/sorcerer of... [[Orcus]]. (Yes, the undead mammalian humanoid Orcus. Why him? Dunno!) Unlike in other settings, it is abominations who rule the yuan-ti castes, and all yuan-ti can create vampire spawn-like slaves through the mingling of yuan-ti and victim blood (funnily enough, both of these would become the status quo for yuan-ti in 5e).
*'''Sura-Khiri''': The besieged forest kingdom of the elves of Ghostwalk, Sura-Khiri has suffered for many long decades from an invasion of yuan-ti from Coil. Thanks to the vagaries of planar dynamics, Sura-Khiri's forests and jungles are the easiest place from which to access the Material Plane from Coil, where everything is infested with snakes and the yuan-ti lack for souls. Now, after many years, the elvish population has dwindled to the point of extinction, and the majority of the population train as fighters, rangers, and rogues. What few elves still bother with magic, which is ineffective against the naturally spell-resistant yuan-ti, tend towards the faster and more battle-ready sorcerer class rather than following the lengthy study of wizardry.
