Photia
Although the ages of the Vadi are unknown, Photia acts the oldest compared to her fellow Deities. This knowledge is known thanks to the ancient Tartyn who have seen all 
of the Vadi when they were awake nearly 400 years ago. Photia was observed as bossing around the other Vadi, especially Sados, whom she sees to have a more familial, brotherly connection with over Eire and Edall.
When she still roamed the underground tunnels of Tynogeum, she was a magnificent dragon-esque creature the size of a mountain who usually wandered the edges of the cave system. She would shift often between liquid and solid form as she patrolled the outskirts of her territory, but would never leave the underground. No one exactly knows why, but it gave many Tartyn comfort to know that a Vadi always watched over them.
Although the majority of her followers are the Nucleus Tartyn thanks to their unique connection with Photia, many other Stellaborn have come to thank and admire the Vadi of fire and lava. Those who follow her usually practice fire magic or carry a pendant of flame to keep her close, even beyond her territory.
