Well, technically, she was a goddess.
The priests were one of the most shocked people in the arena. They were more sensitive to divinity and knew the aura wasn't fake, even though Trantua tried spinning it off as one. He wanted to execute Aaran at all costs, and having a god appear there out of nowhere would irrevocably ruin his plans.
Aaran knew what was going on inside Trantua's head and didn't want him to have any chance of spinning the story. That's why he had asked for help from the goddess, who rushed to her beloved's rescue.
A moment later, lightning struck the ground next to Aaran.
Some people thought it was divine retribution and rejoiced, only to be shocked when the dust and debris cleared. A child with glowing blonde hair was nestled in Aaran's arms.
The priests gasped, while the newly appointed head priest fell off his seat, both in fear and admiration.
A goddess has descended on their measly world.
A goddess who was contracted by Aaran.
