Do you think after Endwalker there will be time travel?

I wouldn't be surprised at all to have voidsent showing up. Buuuut I don't think we'll be going to the 13th unless it's like, a quick visit in a dungeon or something.

We're already hitting Thavinair, Garlemald and the MOON. I think it'd be kind of silly to also have us going to the 13th in any significant capacity this expansion as well.

Exactly - we won't be going to the Thirteenth for one simple reason, we have already been there once before (it's the World of Darkness), and as it's the Void, there is virtually nothing there other than a few ruined platforms/structures and a whole lot of Voidsent. Even the means we used to travel there is now permenantly sealed

(the portal to the Void collapsed when the Covenant the Cloud of Darkness had with Xande was broken once Xande was killed, which required the Ironworks to brute-force the portal open with magitek so we could travel there to save Nero, Doga and Unei, but they couldn't hold it open indefinetely, and it's now permenantly closed).

Theoretically the Crystal Tower in the First could potentially travel there, but again the

mechanism that turned the tower in the Crystal TARDIS was deactivated for good during the events of the Twinning (to be fair G'raha actually planned to use the tower to travel to the Thirteenth himself on a one-way trip as the coda to his plan to save the WoL and the worlds, by absorbing the corrupted Light aether from the WoL into the Tower, and then taking it and himself on a suicide trip to the Void where he would vent it, resulting in the tower's destruction - of course a certain trigger-happy Ascian threw a big spanner in those plans though.),

so that option is out too.

Really I don't see us doing any further Shard hopping, because it serves no purpose once Zodiark is defeated - there will no longer be any risk of Calamities occuring so no need to travel to the four remaining Shards. We'll have more than enough to deal with back home on the Source.
