Ireland
Location
Across the western sea — home to Slane's monastery, and the threshold nearest Tír na nÓg

Historical Accuracy
The exile of Merovingian child-heirs to Ireland (Childebert II in Book IV, Dagobert II in Book VI) draws on the Chronicle of Fredegar's account of Dagobert II's real historical exile to the monastery of Slane by the mayor Grimoald — genuine history, not series invention. Brú na Bóinne, the Dagda's mythological dwelling, and Tír na nÓg as the mythological land across the western sea are all real elements of Irish mythological tradition; the specific events the novels stage there (Merona's rituals, her meeting with Manannán mac Lir) are original fictional elaboration layered onto this real geography and myth.
Historical Significance
Sources:
- Chronicle of Fredegar, on the historical exiles. Broader Irish mythological tradition for Tír na nÓg's association.
Ireland's early monastic tradition — including the historically attested monastery of Slane, used in this dossier as a place of refuge — made it a genuine haven for political and religious figures fleeing continental instability throughout the early medieval period, distinct from and largely insulated from Frankish court intrigue in a way that gives it real historical grounding as the series' place of safety for endangered Merovingian heirs.
Historical Era
Book III, Book IV, Book VI
Novel Canon Role:
- Book III (Spear of Lugh): Merona, Murdach, and the Morrigan travel to Brú na Bóinne, the Dagda's sacred mound, where Merona must wait for the winter solstice dawn to send light into the passage chamber and awaken the triple-spiral power of the Tuatha Dé Danann within her. Elsewhere on Ireland's coast, Merona summons and meets her father, the sea god Manannan mac Lir, for the first time.
- Book IV: Childebert II is hidden at Slane. Book VI: Dagobert II is exiled to Slane by the mayor Grimoald — the Canon's own dossiers flag this reuse across two generations as a striking real-world coincidence of geography.
Site of Brú na Bóinne (Síd in Broga), the Dagda's home and a sacred passage-mound where Merona claims the ancient power of the Tuatha Dé Danann at the winter solstice (Book III).
Where Merona summons her father, Manannan mac Lir, Lord of the Seas, from the ocean and meets him for the first time (Book III).
Sheltered two exiled Merovingian child-heirs across two generations, both at the monastery of Slane — Childebert II (Book IV) and, a generation later, Dagobert II (Book VI).
Geographically and culturally distinct from Frankish Gaul in the series' own visual and tonal register.
The real-world landmass nearest the mythological Tír na nÓg in the series' Celtic cosmology.
