Rise of the Ravenborn tells the story of Baldur, once a young man with a different name from Earth, reincarnated into the mystical, fantastical world of Nunera. However, rather than being a person of renown like a hero or saint, he manifests as a being both feared and repulsed by the populace: a Ravenborn.

However, when he is dramatically saved by a young man named Aquilax, Baldur gets another shot at life, with the two joining forces to embark on adventures and make a name for themselves in the harsh world of Nunera!
