[b]Name:[/b] WIP

[b]Title[s]s[/s]:[/b] Celestial Trinity

[b]Age:[/b] It's complicated. Somewhere between 25 and 200.

[b]World:[/b] 
In a world where magic and technology were indistinguishable, and Celestial Avatars ruled over them, colonizing an entire solar-system was of no issue. [i]Expanding[/i] the solar system became a plausible concept. It was a world inhabited by citizens of the stars. Was.


[b]Race:[/b] Human-ish
[b]
Form:[/b] Watch me WIP, now wa-

[b]Legend:[/b] 
A people capable of not just terraforming an entire solar system, but adding onto it, would seem unstoppable. However, doing so was tantamount to chumming the water. It was as if space itself took form and began to close in on them. A great, glittering ink-blot that wanted to swallow all of creation. 

The Celestial Avatars could only slow it. The power of their sun was all that kept it at bay, but its power could only be stretched so far, and without the planets and moons that orbited it, the spark of magic within the celestial body would be weakened, leaving even it vulnerable. 

So the Avatars surrendered themselves. They gave up their power, hoping by transplanting it into their people that it could grow beyond their current potential. It was all concentrated into three siblings; a boy and his two sisters. Earth, Sun, and Moon. At first they seemed like any other, fighting against the beings spawned by the encroaching void. However, their powers grew and grew, until they were far beyond their peers.

It wasn't nearly enough.

There was one last trial they needed to conquer in order to reach their full potential. They needed to transcend beyond what they were and reach a level beyond the original Avatars themselves. They needed to go to the heart of the first moon; a place that embodied all that was celestial. A place that mirrored sunlight in the darkness and was solid ground, but was neither the sun or earth.

Deep within it, within its raw essence, time did not flow the same. It was an agonizing, lengthy journey, and each time their earth eclipsed the sun, the moon was left vulnerable, letting their enemies pursue them. The combined stresses of the Lunar Core and their enemies was too much. The brother, his powers always the weakest and most mundane, could not keep up. Under the harsh conditions, his sisters had to protect him despite already being pushed past their own limits.

It was at this lowest point that the answer was stumbled across. As sisters were on the brink of falling, he strained his abilities to the max in a seemingly futile attempt to sustain them for a few moments longer before he shared their fate. Instead, their powers were drawn into them, turning three into one. His powers, while themselves the weakest, could channel those of his sisters. It was a state of being beyond anything the Celestials had ever imagined. 

Their enemies were vanquished. Their seemingly endless journey brought to a swift conclusion. 

Finally, the void itself pushed back and all but vanquished.

[b]Will:[/b] Complete disillusionment of the beings that were supposed to protect them.

[b]Mastery:[/b] The brother is a sort of living nexus, with a mastery over the essence of earth, manifesting most powerfully in the form of crystalline constructs. He can set loose one of his sister to join him on the field of battle, enhancing their shared power from the backline. Or, while they remain fused, he can unleash their full celestial might, albeit at great costs to his physical wellbeing.

The first sister, with Lunar based abilities, can create mirrors and portals, as well as magic that controls water.

The second sister, with Solar abilities, has powers of heat and light, but perhaps surprisingly not fire itself. Instead of fire, she has a powerful control over gravitational forces. She also has strong regenerative abilities. The strongest of the trio.

That doesn't mean fire is off the table, however. With their powers now fused, their trump card is the "Sol Gate" which unleashes an apocalyptic stream of solar flames.

[b]Ascent:[/b] 
"It is time. The battle is won. You may return what was gifted." The shriveled shells of the Avatars stood before him.

"What will happen to them?"

"Without our powers within you... you already know." They bowed their heads solemnly. "It was a long battle. You may rest now. Return the responsibility to us."

. . .

"Why?"

It was as if time ground to a halt. Was this... defiance?

"These powers were not meant for you or your kind to begin with, and have now grown further. Return them to us, and-"

"No. You could have stopped this. You put this on our shoulders because the price for you would have been too high. You could have combined these powers yourselves, but you would have lost yourselves. You put your identities over all else." The air around hem grew unbearably hot as what seemed like a small sun began to form. "So I'll ask again: Why?"

"But it worked!"

"Yes. It did. So we'll wield this power now. [i]You[/i] can rest." The small star burned ever brighter, its sinister heat intensifying.

"You can't possibly seek to destroy us with our own power!" The husks recoiled.

"I would hope not. That would just be pathetic." He looked down upon them with a derisive stare. "But... then again..."

And pathetic they indeed proved to be, but to slay a higher being, even ones so reduced, is considered a profane, heretical act from which reality itself may recoil...

[b]Ephemera:[/b] The Lunar Core resides within his body, pushing their magical capabilities to new heights. 

[b]Theme:[/b] Pick a theme song, a battle song, a motif, all of the above, whatever. Try and be creative. You know you want to.
