Start with the Sky.

Of course, Laron realized, the clearest answer was to begin with her previous home, Skyloft. It was time to let the people know they had been saved. With a brief effort, Laron changed the wind patterns and flew directly upward, through the thick barrier clouds and towards Skyloft. It was only now that she realized just how enormous she was. The entire island of Skyloft was now only twice or so her size, and the people living on it were so...small. Insignificant, even. Nonetheless, it was time they heard from their new ruler. Clearing her throat, Laron cast a spell to let her voice reach the entire Sky. "People of Skyloft! May I have your full attention!" With that, she waited, and soon a crowd had formed outside, all of them staring at Laron's sexy, goddess body. Laron could barely hear them talking, but not what it was they were discussing. Most likely, she thought, they were trying to guess her measurements, which she would never reveal. Once the crowd was large enough, she continued, "My name is Laron, and I was once known as Faron, the Water Dragon, a servant of your goddess. However, after assuming great power of my own, I have realized that your goddess has truly abandoned this world, and it is time for you to have a new goddess."

The people below made sounds that Laron could faintly hear, but they were certainly cheers at her ascendency. "I have already disposed of the Demon King who attempted to destroy your world, and I will continue to protect you all as long as I shall live. Which is, of course, forever."

All of a sudden, an enormous voice, one just as loud as her own, split the sky. "What are you doing, Faron?!" Out of nowhere, an enormous whale creature, Levias, appeared. "You are not meant to take power! You are no goddess! I am their goddess-appointed guardian! And what is this dark power I sense it you? It resembles Ghir-"

Tired of his talking, Laron noticed that the once great sky whale was, in face, almost half her size. An idea appeared in her head at that realization, and she knew it was the best way to end this quickly. Swiftly, she reached out and grabbed Levias by his head, and pulled him closer to her. Then, opening her mouth wide, she shoved the beast down her throat, swallowing his enormousness in one gulp.

Just like the last time Link, no, Laron had swallowed a magically powerful being, she felt herself change immediately. For one thing, she grew even more enormous, easily the same size as Skyloft itself. Her breasts and ass expanded out in proportion to the rest of her, and her stomach became a little pudgy, likely from that sky whale's blubber. Laughing uproariously, Laron realized she was even more powerful now than she had been before. "Do you see now, humans? I am your goddess!"
