Timetravel Guru
The girl was crying, thinking of her lost love. In her heart she knew that they should be together. But another girl had already taken him.
In the future a old figure is standing in the desert, watching the sun go down. Thinking of what needs to be done, or what he yearn to become. Infact he was a Guru, with a mission, a mission of the heart.
Many times the guru had traveled in time, finding missing info about the events he would be changing.
