Title: The Citadel of Weeping Pearls
Description: The Citadel of Weeping Pearls was a great wonder; a perfect meld between cutting edge technology and esoteric sciences-its inhabitants capable of teleporting themselves anywhere, its weapons small and undetectable and deadly.

Thirty years ago, threatened by an invading fleet from the Dai Viet Empire, the Citadel disappeared and was never seen again.

But now the Dai Viet Empire itself is under siege, on the verge of a war against an enemy that turns their own mindships against them; and the Empress, who once gave the order to raze the Citadel, is in desperate needs of its weapons. Meanwhile, on a small isolated space station, an engineer obsessed with the past works on a machine that will send her thirty years back, to the height of the Citadel's power.

But the Citadel's disappearance still extends chains of grief and regrets all the way into the fraught atmosphere of the Imperial Court; and this casual summoning of the past might have world-shattering consequences...
