Many years ago in the City of Rome,

there was a vast epidemic of disease spread by unhealthy drinking water.

Fresius, shook by the death of her entire family and all of her friends, was determined to do something about it. Though she herself had little power, she reached out to the gods in search of help.

After visiting an alter to pay homage to the gods and request aid, Fresius heard a voice from the heavens. The voice identified himself as Neptune and then told her that the answer she sought was at her house.

Originally baffled by the thought that a god like as Neptune would listen to the prayers of a peasant such as herself, it occurred to her that the gods draw their power from the prayers of the mortals, and if there is nobody alive to pray, there is no power.

When Fresius reached her shabby little house, she found there to be an abundance of seashells on the floor forming a trail. When she followed the trail, it lead up the stairs to a chariot made of mist on the top of her house lead by a brilliant white pegasus.

I will name you Elepius!

What do you want of me!?!?

Confused, Fresius cried out to the gods and waited for a response.

Board the chariot. Elepius will fly you to a storm cloud outside of the city. There lies Zeus's eternal spring I once gifted him. He has agreed to let you use it to supply and clean Rome's water. Beware of the storm spirits guarding it though.

Neptune's voice spoke once again from above.

After a long journey through the clouds, Fresius reached the spring and as promised it was surrounded by venti. The storm spirits encircled her but she was prepared as she had brought her trusty lance.

She slashed and jabbed and vaporized every ventus there. She set the chariot down in the spring. Elepius drank, but so did the chariot. Slowly, it transformed from mist to water, and the spring did not empty any.

Once the chariot was completely full of water, she boarded it and set off back down through the clouds towards Rome. As she broke through, she saw an aqueduct below.

Maybe I can empty the water into the aqueduct and it will clean the water supply.
