The death of Orisis was caused by jealousy because his brother was a king and Orisis was the ruler of earth, and so Seth decided to kill Orisis so Seth can be ruler of earth.Seth wanted Orisis place because he had a stronger and more power thrown and Seth had a less powerful thrown so Seth got angry.When Orisis died he was sent to the underworld, but there was still one more son Horus, Horus got angry an decided to kill Seth because what Seth did wasn't right or fair,Horus also decided to kill Seth to regain Orisis thrown.Horus soon became ruler of Orisis thrown because Orisis couldn't come back to life so Horus took over.Horus regain Orisis thrown by challenging Seth and won by killing Seth, so Seth ended up dieing like Orisis.Orisis became ruler again but not of the earth he became ruler of the underworld.Orisis became ruler of the underworld because he was getting sort of known and became ruler.

When a person dies in the myth stories of the gods people go to the what is called the underworld in the story the underworld is under the world of course, and so that's where Orisis went.Orisis was dead so he could not come back up to earth to regain his thrown, so Orisis sent Horus his brother.Horus was sent to kill Seth for what he did to Orisis witch was not a good thing to do so Seth wasn't a good person.Orisis wanted a just and nice ruler to take his thrown so that's why he scented Horus, so he did what he was sent to do and battled Seth and killed him.Orisis was not frustrated any more because he got revenge and took back what was given to him, so everything turned out to be okay and things went from bad to good.

So what sort of happened is like the expression what goes around goes back around and so then Seth got what he deserves after all.Orisis went to the underworld and so did Seth.Seth ended up with nothing,but Orisis did by becoming ruler again and now Seth isn't king or ruler of any thing.Seth now pays the price because of his actions and every one turned out to be happy.
