In the centre of Lviv, tiny winged girls and boys live on the roofs - city elves. These are city elves. Each of them has its own tower, its own work and joint entertainment in the air.

One day, their carefree life will come to an end. The city dungeons will be invaded by mutant rats that will threaten the entire city. Not only humans and minstrels will have to defend themselves.
