Tine is a fire spirit, she’s a lot like Saol. Her appearance and behaviour depends on her surroundings too, in a safe environment she’s just a playful spark or a small flame that might annoy Saol a bit but doesn’t harm anyone, but after a long and dry summer she grows bigger and bigger and becomes more voracious and unpredictable. Saol didn’t let her burn too many things and he put out the small flames as soon as he could with wet mud and dew drops, but things changed somewhat when Tine realized that offering light and warmth to humans turns them into loyal servants who always feed her no matter what the nature spirit says or does.
She didn’t expect them to turn on her though. In a few centuries they started building machines and then chained her into those machines to fuel them and make them do the work instead of humans. She was raging but couldn’t do much but obey.
Ever since then, whenever she sees the opportunity to get out of her chains she does so and devours everything with boiling hatred until nothing remains but ashes and smoke.
