Arthur stared at the beautiful creature in front of him, who was pleading for him to leave everything else behind. But, in the infinite time he spent with Gaia, he learned that his past self was a close friend of one of the guardians, God of Life, Lyari.
This gave him an idea to manipulate the guardian into becoming on his side, but Arthur was not that kind of person, although he needed to be. However, this was not the most challenging question.
"I have an impossible choice to make."
Lyari was quiet as his eyes drew crescents, the long eyelashes trembling. Arthur stared above at the myriad of colors as he mulled over his choice.
"However, I don't think it's even a choice."
Arthur realized as he thought deeply about it. It was a yes or no question, and refusing to give them his powers would result in him never having the ability to choose anything. His choice was given because he said yes before, and he needs to do it again.
