7E: Create the first of the Black Cities, inland of Pan Tobuersha. The first shall be named Vaekhem, and their kind shall be known in the Engineer's Tongue as Mul Vaekhem. Living marvels of architecture, machinery, and urbanization, their relationship with the Technicians is uncertain, though some believe they control the Technicians, this has no real observable basis.. What is known is that Technicians are often protective of the City if it is being damaged in a non-superficial manner, though the degree to which they pursue this varies greatly. Black Cities are essentially mechanical organisms that greatly resemble semi-mobile, self-assembling cities. Their 'life cycle' is poorly understood and largely dependent on smaller, sentient organisms, as they are not sentient on anything resembling a mortal or understandable timescale. Only mobile during part of life-cycle (when smaller), unable to 'reproduce' unless sedentary.
4E: Create the Technicians, within the Black City of Vaekhem. It is unclear to mortals what their connection to the city is, though their name stems from the fact that they usually appear to be doing maintenance work or upkeep of some kind. Those who interfere with their work, however, rarely fare well, and by all accounts appear to have no end in numbers if a position to slay them is taken up. It's also uncertain from where they emerge or where they return to when they feel their task is complete. Technicians will usually ignore any questions asked of them, though some will respond with very general answers, always in the Engineer's Tongue. They refer to themselves as the Böd Jura, which translates best as the Technicians. Usually, though, if thye say anything, they will respond by informing the asker that they are performing maintenance.
