While on horseback they travel the country Thorgal and Aaricia meets the dwarf Jadawin who leads them to the land of Aran, a small village, at the edge of a lake without bottom, or drag, as worn out, its inhabitants with empty eyes of expression! In the middle of the lake stands a castle occupied by three old men who end up capturing Aaricia by irritating as the new queen of their estate. Thorgal will have to win back his dulcinate after having had to pass for it a lot of tests.
