"Covenant of Finality" is it? That should be the dancing cutscene part of the chapter.

That mission mean complete main story chapter I part 2

Okay, then the wording might have been changed. But what exactly is your issue? I don't get it.

In my screenshots you can see which menu you have to enter to go to chapter 1 and that it has multiple sub-missions. Chapters 1 to 3 of part 2 are open world. You enter the open world and do quests as they go. There are no stages you can enter or clear-cut chapter selection like in the early days.

Do you not see the Tides of Time Gone By section when clicking on Extinguished Starlight and Rekindled Fire tab?

Hmm Covenant of Finality

Ok thx you I think my problem is solved
