From the publisher's website:
Welcome to Faerûn, a land of amazing magic, terrifying monsters, ancient ruins, and hidden wonders. The world has changed since the Spellplague, and from this arcane crucible have emerged shining kingdoms, tyrannical empires, mighty heroes, and monster-infested dungeons.
The Forgotten Realms Player’s Guide presents this changed world from the point of view of the adventurers exploring it. This product includes everything a player needs to create his character for a D&D campaign in the Forgotten Realms setting, including new feats, new character powers, new paragon paths and epic destinies, and even a brand-new character class never before seen in D&D: the swordmage!
