Eurydice ran through the forest but tripped and fell onto ground. A snake was right were she fell and it bit her. She died right when she was bit.
As soon as Orpheus found out she was dead he traveled to the underworld to find her.
He made it all the way to Hades and tried to persuade him. He played music and finally persuaded him. Hades said if he looked back at her on his way back to the mortal realm she would go back to the underworld.
So they stated walking and Orpheus wanted to look so bad. At the last few steps to the mortal realm he turned to look at her. She immediately returned to the underworld.
Orpheus was so devastated that he started to break his instrument and it made a really annoying noise. The people who lived there could not bear the noise so they ripped Orpheus to shreds.
Now Orpheus floats down the river and tells prophecies until the world ends.
