Prestige Class Additions

I have added 2 prestige classes to the Atepesh region on the Classes page. The Sand Shaper is a sorcerer prc and the Scorpion Heritor provides unique options for rogues while maintaining the high skill point allotment.

Edit: Several new classes now appear on the list. Orc Scout fills out the Nubiwatep region (listed under Atepesh), Giant-Killer appears on the Halmland list, the Peerless Archer provides elves with some ranged punch, and the Mystic Wanderer fits into the Keldari way of life nicely. Some of these classes require some 3.5 updating or general balancing, but I will not list those updates until it becomes necessary to do so.
