Arbert Otheth
A noble (IDK what the right thing would be for this but I'm down with whatever) charged with planning and constructing new settlements when and as the Dawi Zharr population swells enough to merit such a new construction, it is a bleak order he forces on the fallen Ancestor spawn; a cruel, alienating, breaking thing, forced at the edge of an ax. All things are designed to make life easier and simpler for the rich and powerful of the Dawi Zharr, a time to luxuriate in the wealth and privilege they have acquired. Streets, systems of transportation, and more are all designed to be near uncrossable if one lacks, at least, a good sturdy sedan on which to be carried; better still some bleak daemon engine. If such street design costs the lives of a few thousand slaves, well there are always more to be claimed from the greenskins and the humans and the elves and the Skaven and more. The poor, the few foreigners, and the slaves are kept in vile accommodations themselves, in descending order of deprivation, so as right proper folk do not have to deal with them. Industrial facilities are ringed around those quarters, so that the high and powerful are not forced to deal with such in their mansions and lap of luxury; and if slaves and the poor are forced to inhale dangerous, toxic, fumes, well so much the better.
(TLDR: American Urban Planning: Hashut approved!)
