The city of Finias is referenced most often in Pagan/Wiccan rituals. The ancient city is associated with the element of air and the eastern quarter.

Is it said that one of the sacred items of Paganism, the Sword of Nuada existed in this city.

From an actual Beltane ritual performed this year:
From the halls of Finias, mystical city of old, we call upon the powers of Air, you who bring us clarity and wisdom, descend from your aerial realms and be with us. May the sacred Sword of Nuada protect and keep us.
