Not very sure if this is good enough, but eh....

And so you shall change...
The Crymits of the city fell asleep, wherever they were; in their homes or in the streets, they dropped and fell. They dreamt of fortunes and unimaginable truths and lies, power and weakness, the future and the past. And yet while they slept, the god of labour worked on their living shells.
He changed these bodies, these mortal husks; he made them hardier and light in weight and turned them all a azure blue. He then went to work on clearing out all the bodily organs within these mortals, making sure to keep the souls of the creatures alive. The god replaced this flesh with...well it wasn't natural. It was gaseous and a strange blue, but it seemed...intelligent. These would replace the shells of the Crymits; the perfect workers, not needing rest.
As for the souls of these creatures, Omoloth worked hid them for a decade, while their former bodies worked to dig the city out. He worked on them, tampering with them, changing them in entirety. And as the decade passed, the souls reappeared. Not as the Commoners and Emperors of the Crymits, but something else entirely. They were Shrouded Figures, just moving robes, no body. They could speak, laugh and could animate their robes to simulate gestures...But they no longer had bodies. But they gained something else; functional invisibility and intelligence beyond what they could ever dreamed of. Commoner and Emperor alike, these were smarter. These figures appeared throughout the Crymit lands, presenting themselves to the leaders of the cities as Ascendants, envoys of Omoloth and would act as direct conduits to the god, effectively allowing any commoner to speak with their god. In addition, they would happily advise any who would ask...
As for the husks or shells, these strange constructs would become constant bodyguards for these Ascendants, as well as aiding the cities if commanded to by their Ascendent.
Regardless, these servants of the Labour god would become feared or loved, depending on the person. Some wondered why and how these servants appeared, some even correctly linking them to the buried city in the north. Of course, these servants never revealed a fact about their origins. While not replacing the Emperors, they would change the social structure of the species forever.
