When Elijah died, everyone in his sire line died with him. I don't think the Strix had no way to reach him at the bottom of the ocean. Maybe we will see what happen to Vardemus.

Ur probably right

But here is the whole list of people i consider mystery status:

https://vampirediaries.fandom.com/wiki/Category:Unknown_status

Do we consider the ancestors of new orleans to have a mystery status?, i mean i guess we have to assume vincent and the others took them away with that giant light ball but we didnt see them sucked into said ball

There is a couple of new orleans characters that we dont know about-joe, charlotte, the guerreras, the witches who helped kol, the kindred, nandi and her mom were also in that category

There is a ton of vampires we dont know about if they are dead but they basically no names

Silas's cult-kol only mentions he killed them, we didnt actually see them die but im inclined to believe him

The gemini coven-yes we saw them drop dead when kai killed himself but some of the coven could have unlinked themselves, doubtful but not impossible

The travellers-yes we saw damon blow them up but again maybe some got away, maybe some were cast out of the coven and never made it to mystic falls

Ansels pack-only mentioned to be killed by mikael, he probably did kill them

Well we wont truly know until we find out from kai which worries me cause kai is a liar

I personally do, maybe u dont

The Ancestors are presumably at peace or just sitting in the afterlife because after the Ancestral Plane was destroyed they were forced to move on or just I don't spectate or whatever

I would consider them a non factor if they were only kept in new orleans being we arent there anymore

However because it turns out they can leave and still operate with magic implies to me they might become a factor

I want to learn for sure that Katerina found peace.

Yeah i get what u mean

Why do you want to know the outcome of everyone and their mother? That takes time away from the story and is basically adding nothing to the story

I would like to know what happened to a few of the people who passed away too but I don't think it should be discussed in legacies. I feel like it would be unnecessary to add that kind of information in the show like what @Rai Zor El said it wouldn't add to the current story. I feel like it would only make sense if they discussed it on the previous shows but that choice is not available (because they ended). So I rather it not be spoken about at all unless the information is crucial in the storyline.
