Tiarna Si

The Tiarna Si are the greatest and most powerful of the Sidhe. Resembling enormous beasts with eyes like starlight, the Tiarna Si roam their domains in the Otherworld and protect them; they are able to appear anywhere in the Otherworld instantaneously as long as it is within their domain of power. There are nine Tiarna Si in total, each with a different appearance. 

• A stag who protects the forests
• An eagle who protects the skies
• Three koi fish who protect the rivers, lakes, and oceans
• An auroch who protects the plains
• A bear who protects the caves
• A python who protects the marshes
• A dragon who protects the mountains
