"The power of the spirits doesn't grow with training. From the moment we were born, our strength was limited to our world," The time spirit said. "Things like the number of people in that world may influence our power, but we cannot influence them to make that happen and benefit us. We also don't think that we need that. From the very beginning, we only oversee that world and help the people there survive their hardships. We aren't the ones who have to save it."
