On the other side of the Ekeros River that encircles the earth, where it meets the land of the dark night, there is an old city ruin. The long years have made everyone forget about it. Some ancient texts reveal some traces of the city. It can be roughly inferred that this city was once the capital of an extremely powerful country, whose territory even the dragons could not fly across in ten days and ten nights. On an altar in this ruin lies an egg, which is more like an egg-shaped stone than an egg. The surface of the egg has many tentacles, resembling many small snakes. Grass doesn't grow within a hundred meters around it. It is said that inside the egg might be the legendary snake-haired monster, Medusa.
