You travel to a sacred waterfall to perform a sacred ritual to summon the creature deep within, it was said that the creature had infinite wisdom, power, and charm

Once at the waterfall you perform the ritual, tossing scared flower petal as well as silver and gold

You wait a bit, and feel the ground shake underneath you as you watch a giant pitch black figure with neon green eyes arise from the waterfall peering at you

“Hello little one, what is it that you seek?”
