Lin was young when the goddess extended her hand to him with such an enticing deal.
Without outside help and the knowledge of the strange disease, Lin couldn't save his village. He has only been leading the village for a few weeks, and his father has left him in the drop of a hat. Those who could guide him have followed his father or are too weak to oversee any procedures.
So what if it is a weird request? The goddess is not asking for someone's life or anything that harms others. She is a goddess, right? She should have her reasons.
"Where are you sending me?" Lin asks timidly, still too scared to lift his head to face the goddess.
"It doesn't matter," Vita replies, "I will bring you back here once you have finished the end of your bargain."
'Doesn't matter? But I am going there! Of course, it matters!'
