In winter, walking through the forest, you found a dirty black egg near the bushes, which is indistinguishable from a stone. After taking it home and putting it on the incubator, you started waiting. A week has passed since that moment, and in the evening, sitting in your room, you heard the incubator shaking from the movement inside. Getting up and coming closer, opening the lid of the incubator, you saw a black and long dragon frozen in fear in the corner of the incubator apparatus.
