Aridia Arthima is a young recruit of the Royal Guard of Alia, capital of the kingdom of Meridia. She lives peacefully with her family in a manor inn in the richer quarters, with her father, the king's personal magus, her mother, an archaeologist and innkeeper, and her three sisters, of whom she is the eldest. Her hidden dreams of adventure, and her boredom, of which she is not yet aware, will be disturbed by the arrival in the inn of a strange stranger of the mystical race of the Athrians, who appeared suddenly a short time ago in front of an abandoned mausoleum in the marsh surrounding the city. This being nicknamed the traveller, amnesiac and bearer of a dire message in the form of an enigma that he himself does not understand, is looking for a company of mercenaries to help him solve the mystery surrounding his identity and the link with this mausoleum.Driven by her last sister's curiosity and her own thirst for adventure, Aridia will find herself at the side of mercenaries from the four great countries, and the strangest family of Athrien, facing a strange cult led by a half elf and undead witch who has come to liberate an infamous being from its stone prison and reveal the greatest secret surrounding the Athrians and their appearance in this world, more than a thousand years old.
