Numinex

Numinex Was a Dragon that was fought by King Olaf One-Eye atop Mount Anthor in Skyrim.

King Olaf kept the dragon in captivity as a personal pet in Dragonsreach, which was built to house the humiliated beast. After it died, its head was removed and placed above the fortresses' throne, where it has remained up even into the events of The Elder Scrolls V: Skyrim.

Trivia

 * Paarthurnax has said that he would visit Numinex during his imprisonment and that Numinex was so lonely and disturbed by his captivity that he could not remember his own name. How Paarthurnax was able to visit Numinex and escape without notice or why he didn't try to free Numinex are never explained.
 * Numinex is the subject of Skyrim's first revision to King Olaf's Verse during the end of the quest "Tending the Flames".
 * Dragons in Elder Scrolls are immortal and it seems that Numinex's death was natural although, it is stated by Paarthurnax that he was lonely and distirbed and he could not remember his name, this may be the cause of death.
