I Got Stucked In Mission Please Help

Hey, I was doing "Fate of the fallen" mission and I died, after that I respawned in Ternaves and I don't know how to go to that place again to finish the mission. That place is supossed to be in the past... so i dont know how to reach these place,

 

Try following these steps:

• Return to the Nesaak bank and grab another Theorick Staff.
• Return to the door of time on either foot or horseback.
• Enter the temple of time, and throw your Theorick Staff in that one hopper.
• Repeat all stages that take place in the past until you reach the place where you died.
