you know i can see the MC having a harem where all the girls are the personification of the 9 worlds. and you could use the Eilom (the light elves dimensional space) to infuse into a light elf to give birth to a goddess of light, life, and infinite energy. you could also use the Eternal Flame and craft a elemental hearth goddess for the fire demons, and the casket of infinite winters for the frost giant (with a personality that matches the joy/wonder of winter)
