glossary

Eidrheim, the kingdom at the center of Realm of Oaths, exists in a world of nature-based magic and institutional faith. Below is some terminology that is used throughout the story.

TermDefinition
EidrheimLiterally "home of oaths", this is the name of the kingdom central to Realm of Oaths. Previously spanning most of the continent during the time of King Rei's rule, its area is halved when King Leo comes into power.
FinheimPreviously the southern half of Eidrheim, Finheim is a collective princedom that split from the main kingdom before the events of the main story. It is mainly governed by Prince Eichi Tenshouin, of the esteemed House Tenshouin.
GuardianOne of five powerful, magical beings that watch over the land and its inhabitants. Each is associated with a single element of nature. Blessed by nature with unique abilities and supernatural wisdom, Guardians are far more powerful than humans, and do not die of natural causes. However, if they are killed, they will be reborn after many years with vague memories of their past lives.
Guardians' WatchtowerBuilt during the rule of King Rei, Guardians' Watchtower is a grand castle that sits atop a rock formation in Laerad, the capital city.
LaeradThe capital of Eidrheim. "Laerad" is also another name for the Norse world tree Yggdrasil.
Music of the LandAlso known as "Song of the Land" or simply "The Music", the Music of the Land is an undercurrent of life force that connects all in the kingdom. Only Guardians can hear this music and play it of their own accord, though some special humans, such as Leo Tsukinaga, are able to hear it as well.
NatureThere are five elements of nature revered among Eidrheim's people: forest, mountains, plains, sea, and sky. Most families, both noble and common, are traditionally affiliated with one of these five and worship the corresponding Guardian. When a person dies, they are believed to return to nature and to the Music of the Land.
Old LandsThe name of the now-forgotten continent across the sea from the Eidrheim mainland. Though Eidrheim peoples used to live there, it is now a desolate wilderness only braved by nomads and pirates. Old Lands people refer to Eidrheim as the "New Lands".
Silent OathAn ancient blade that King Leo uses throughout most of the story. It shines with a dark reddish glimmer.
