The river Seine.
A legend said that Sequana, a lady of supernatural beauty, lived at the source of the Seine and protected the place.
Was she a nymph, a mermaid or a goddess ? No one knew, for the village chiefs had forbidden anyone to approach the sources.
However, on the outskirts of the forest, an unnamed horror had just arisen. Extinct for an eternity, it roared again and threatened to carry everything under the fury of its fangs.
The most incredible story in the days of the first Celts in France.
