One-hundred years prior to the events of the story, the Leymon's country was destroyed by a civil war, and the race was eventually overthrown by humans. This forced the Leymon to go into hiding, donning human forms and secluding themselves to the most inhospitable regions of Areulla. They lived in peace this way for many years until the Pope ordered for them to be hunted and killed.
- Lycanthe is a derogatory term that humans use for the Leymon, propagated by the Church to influence public opinion toward viewing them as monsters. It is derived from the term lycanthropy, a werewolf shapeshifting ability that serves as the basis for the Leymon race.
- One of the areas of Holy Midgand Empire in Tales of Berseria is called "Leymon Sea".
