********************************************************************************************************************
Hestia, the God of the Sun, has a son named Omega. Omega grew up to be very spoiled, he never wanted to help clean or do the chores. All he did all throughout his life was cause trouble everywhere. He purposely knocked market carts full of crops over, he played pranks on everybody, he cheated on games, and he dug up flowers in the garden. He did even worse things when people made him angry. Hestia didn’t appreciate his trouble and did not want to deal with it.

Upon one beautiful, yet hot, summer day, the Great God Hestia, was yearning for a drink. He knew that he could of simply asked for one, but he wanted to test Omega. Hestia called for him, and told him, “I am thirsty. The nearest source of water is the small river in the whispering sands desert. Omega, I want you to walk to and from the desert with only one goblet to fill with water, for me and not you. I expect the goblet to be full when you return; no water shall be drunk nor dropped from it. When you reach the river, I know you will be thirsty too, so you may stay there for as long as you want, but listen as I tell you this; once you leave, you may not turn around to go back and drink more from the river.”

Omega, who was barely even listening, said “ Sounds easy enough, I do not understand why you explain to me so it seems like a hard challenge.” But Hestia just shook his head, and handed Omega the goblet.

So off went Omega, into the vast desert. He walked for about 7 hours, and then realized that his skin began to blister and turn into a dark red color. He was very nervous about this, for he had never seen this happen to his skin. He ignored it though, because then his focus became into finding water. His throat, mouth, and lips began to dry and wrinkle up.

He tried to ignore both of his problems, and after a while he came to the river. He was overjoyed, and began to splash, play, and swim. After a while, he got out and filled the goblet. He thought to himself, “I feel refreshed and ready to go back to Hestia.” Omega walked two steps, and then thought that he should go back and drink some more just so he could have even more energy. But as he tried to turn around, something wouldn’t let him. After trying to figure it out, he remembered what his uncle had said, “Once you leave, you may not turn around to go back and drink more from the river.”

Omega didn’t worry though, because he knew he drank enough water to get him through the rest of the journey, but he did wish he could get some more water in his body. But he continued to walk to home. Again, after a while his skin started to turn red, and it burned if he touched it. He wondered what it could be. His mouth started to tighten up again from lack of water, but there was no water around except for the water in Hestia’s goblet. He thought about drinking it, but he knew that if he disobeyed his uncle, there would be consequences.

An hour later, he desperately needed a drink. He had no choice but to drink the water in the goblet. So he drank three tiny sips and put some on his red skin, to cool it down. As Omega looked into the goblet, it was clear that it was no longer full, as the God asked for it to be.
Omega continued to walk, hoping that his uncle wouldn’t notice that his cup was not filled all the way. He finally got to the palace, and Hestia said, “ why isn’t my cup filled the to the top? Did I not ask you to fill it all the way ?” His nephew was scared to answer his question, but he responded with, “Yes, but I started to get severe burn-like blisters on my skin.” “I SAID NOT TO TAKE ANY OF THE WATER FROM THE GOBLET!And you did!” , said the god, “ And now whenever you go out into the sun or any hot weather, you will continue to get blisters and burns on your skin.”
