Oisin

Oisin was an Irish poet and a lover of Niamh.

Background
Oisin was a poet, who through unknown means discovered the future site of Aeternis. Back then it was a system of caves, overlaid over an extensive network of ancient tunnels. In the caves, he found Niamh and spent a year with her, teaching her how to read, write, and telling her the history of his people. Then Sasha returned and he left to return to his people. Niamh tried to follow him, but the long years in the caves and the influence of grailstone rendered her vulnerable to sunlight. Oisin left, promising Niamh a reunion in the future.

Interactions

 * Although Oisin himself does not appear, the amulet he wore can be found in Niamh's chest in the mine maze. It can be used to ward off Sasha.

Behind the scenes

 * Oisin is the second part of a reference to the Celtic myth about Tír na nÓg and was written as such in the design document. Her role was only slightly altered: She was originally a Byzantine tribeswoman, not a Pict, and her ghost would be encountered in the chapel, where the guardians would have interred her.
