Death of the Dragon (The Cormyr Saga)

Azoun IV, in the twilight of his years, is still a shining hero to most of his subjects, and to all but the eldest, the only king they've ever known. He's led them capably out of dark doom before.

Yet Cormyr has never faced so many mighty and mysterious foes at once. Demonic ghazneths, ancient curses, weird trees of foul magic, goblins and their kin on the rise in the northern wilderlands, a blight upon the land, rebellious mutterings, dying war wizards...and a dragon the likes of which no living eyes on Faerun have ever seen.

The Purple Throne doesn't seem so unassailable now. It could well shatter under the weight of a gigantic dragon--or the secrets and follies of the last of the Obarskyrs.
