The storm rushed down the mountain, heading quicker every second. All this tempest lead by Tiamat, in the form of the small bird. It's unfeeling eyes rushed above the different towns and cities, creating different disasters as it passed by. Hail, lightning, tornadoes, sandstorms, and even sleet and snow.
These repentine calamities caused people to rush into their abodes, while others rushed out to see what was going on. These people immediately regretted those decisions, being slashed and slapped by the strong winds and everything in them. Some people were carried away into the wind, separated from their families, presumably forever.
This was only the beginning of what Tiamat was going to bring to this kingdom. The kingdom destroyed the balance that nature had put in place, and Tiamat was a manifestation of the consequences.
At one point, while flying through the air, Tiamat felt a twinge of pressure rising in the kingdom. The mage had put up a magical barrier. Still emotionless, Tiamat shook it's feathers and brushed it off. No amount of magic could stop it. No matter whether it was done by mortal or immortal.
Tiamat began to track the source of the magic, pinpointing it to the kings castle. Ah yes, of course, the sorcerer. Tiamat simply swung its head and sent a quick, painful message that would ring in their head. Do not get in my way unless you want to be the last to die, in a way your limited mind would never be able to imagine.
Tiamat then felt an actual wince of pain. It sensed something… someone… that was not meant to be there. They were not from there. A painful image burned into their mind. An image of a burning star. The chosen that will defeat the darkness.
Tiamat still did not feel emotion (as you can tell by now, Tiamat simply doesn't feel any emotions. They only care about the balance). They simply needed a way to redirect their plans. Closing its eyes, it projected its spirit into Geneviera. Just as it did this, it saw a metallic flash in front of it.
Before Cassiel could even reach Geneviera, her eyes went black and Tiamat took over her body, black smoky tendrils leaking from her mouth, nose and ears. Everybody in the room began to run out screaming in fear. Acquainting themself to this body, for as little time as it could, it wrapped a tendril around Cassiel's neck, immediately immobilizing her middair. A black mist covered all of Geneviera's face now, and the form of a pseudo-mouth on it began to move.
"So. You are the one fated to defeat me?" it asked, it's voice duplicating with Geneviera's. With metaphorical eyes, it looked her up and down, and said, without a demeaning tone, simply dryly "You don't look very strong." it tilted Geneviera's head "But I am not one to doubt a prophecy. So here is one of my own" The lights in the room dimmed as it began to recount a prophecy.
"When the last of my being disappears from this earth, there will no longer be hope in your heart, your home and your heart will be empty again, as your victory will come from the entire world's pain"
It loosened its grip on Cassiel's throat, allowing her constricted throat to breathe again. "I advise you mull this prophecy over before you think of interfering with my plans. My only wish is to bring balance to the world." dropping Cassiels body, it added a final statement before dissipating from Geneviera's body "Oh, and you can't hurt Geneviera. I granted her protection from all physical harm through our pact."
