I am quite jealous of this book. Eberron gets a psionic continent fleshed out while psionics gets the backdrop in the Forgotten Realms setting. The only major concentration of psionics in Faerun is the long-dead Jhaamdath Empire and its handful of psionic leftovers...
I really wish the FR designers would create a campaign/adventure book detailing a huge psionic adventure involving the rise and return of the psionic deity, Auppenser, and detailing more details on Jhaamdath's past as well...that'd be a great FR psionic book.
