When the Demon-Queen conquered the city of Zangiers her army brought with it a half-dozen monolithic statues of unknown origin. Each some thirty feet high and seeming to depict individual God-Kings in finely carved sandstone, these trophies of an expedition into the deeper Sunamyo were deposited in the middle of the River Oued flanking the bridge of the moon and the dog bridge which together allow access to the northernmost parts of the city, where she would construct her pyramid / palace / temple / fortress.
The figures settled into the sediment and muck at the bottom of the river at odd angles, giving their stony gaze over the bulk of the city to the south a feeling of surreal portent. Like their origin the purpose of placing these strange figures from out of time is unknown, or at best hidden within the depths of the palace with so many other secrets. To the general populace of the city they have become merely yet another piece of the backdrop of their daily lives, hardly worth noticing. But for the visitor new to the city they are sure to inspire questions, and this fuels the many strange tavern-tales as to their true nature.
Perhaps the most oft-repeated of these, and in some ways the most troubling, is the supposition that these are not merely statues at all. Many forms of dark magic have been ascribed to the Demon-Queen over the years, and the ability to lock the souls of those who dare meet her gaze within a stony prison is actually one of the less-horrifying. So it has been suggested that these may, in fact, be some of the ancient God-Kings, or at least some of their servants, trapped by sorcery either as punishment or possibly until such time as she has need of their service.
