Fate Of The Fallen Help

This quest has a portal part and afterwards you get tped to the root of corruption and the bridge gets destroyed. A couple friends and I fell off the bridge an into the lava. we died and we want to continue onto the quest. we go back to talk to Telvu which was the guy that tped us there and the portal is gone and we cant exactly interact with him. Is there a way to restart this quest? Is there a way to get back into the portal?

 

you need to get theoricks staff again. then go back to the house thing and do it again

 

You need to do everything again. When you are finished you will not be teleported, you will need to find a house near the riverbank where you talk to the NPC you will be teleported to the nether port and continue the quest. If you want to go back to the past you need Theoricks Staff and go back to the time door and into you just drop it on the funnel it will let you go back to the past and continue the quest.
