The beginning of the Dark Ages, the western edge of the former Roman world. The young city on a hill, above the river and the sea, has neither memories of the great past, nor fear of the approaching darkness. There is so much work that the water wheels creak from the strain, and in the forges they have to work in three shifts. The ruler also has a lot of worries. Trade affairs, quarrels of mountain clans, high politics... there is no time to sleep! A mistake can cost her life or the city in which she likes to live: looking at the green slate roofs from the tower, running along the stones of its pavements, catching snippets of conversations with her long ears while busy with everyday life affairs of the residents - and, alas, disputes about who she is. “Kholmovaya, sida!” - the Cumbrian will say. “Holy and eternal basil!” - the Greek will say. “An engineer from the future” - the strange creatures who drove her will say - at this time and to this Earth. Who is she really? She doesn't know. She has no time to figure it out. Oh - you have to!
