Oirûnas is a Nonman hero who fought in the Cûno-Inchoroi Wars and is currently imprisoned in the deeps of Ishterebinth. Oirûnas and his twin Oirinas were members of the First Watch on the Incû-Holoinas. When the Inchoroi attacked, Oirinas and Oirûnas were the only two survivors, and rode hard to warn Cû’jara-Cinmoi. After the Battle of Pir Pahal, the two were assigned the duty of recruiting Men for the Second Watch. Oirinas and Oirûnas later engaged the Inchoroi once more on the Inniür-Shigogli, where both were slain.
