Maechen and the black mage dressphere (possible spoilers)

[Little Blue]

Though I would like to challenge that an unsent dream citizen would disappear with the rest of the city. I don't believe they would, and would exist like normal unsents, entities derived purely by pyreflies based on the soul that permeated them in life. Consider that Tidus' Mother is seen in the Farplane, implying that after death, the pyreflies themselves can persist an entity (as an unsent or as a farplane apparition) and no longer need the summoning to keep them together, and we do hear from (SPOILER)Jecht in the final battles of X-2, after the dream had ended, who was a dream citizen.

I believe that in the first game, Pyreflies were termed to be "reactionary" as opposed to having their own entities. Yuna said to Tidus that one can see his mother, because of his memories, not because she was real or any other reason.

Bugger, how silly of me to forget to include that part. Of course pyreflies are reactionary. Though it is not as simple as remembering a person, it needs to be remembering a person who has died and went to the farplane. The pyreflies that existed within that person, real or aeon, likely develop an imprint of their host, and this is what helps define their afterlife. If they end up on the farplane, then someone entering the farplane and thinking of them, encourages the associate pyreflies to gather and form an apparition. Perhaps its some kind of resonant effect by thinking of someone. the visitors own pyreflies calling for the those of someone they used to know and the deceased's pyreflies, or those nearby at least, manifesting in front of them?

That is true, we hear (SPOILER)Auron and Braska too but the battle in question takes place on the Farplane where likely the rules are more lax about unsent ?

We do know that Maechen can teleport inside Leblanc's Chatteau and the Celsius so he is no regular unsent either.

By definition, an unsent is someone who has neither gone to the Farplane, nor accepted their death (IE, they had something left to do). Once you get to the Farplane, it doesn't matter WHO you are, you are no longer an Unsent. Maechen and Auron both fulfill this criteria. As such, there's no such thing as an Unsent in the Farplane. The whole definition is based on an exclusionary theory. You can only be one and not the other. Yuna has memories of Auron, Jecht, and Braska, alllowing them to speak.

This is however not the standard farplane manifestation if we consider the apparitions that appear near the Guado entrance to be standard. Though perhaps that can be accounted for if we consider that massive lecture Yuna stiring a ton of memories or her latent summoner skills somehow playing a part. That or conclude that perhaps pyreflies can form cognisant entities in the Farplane or blame X-2 for stupidity.

However, there is precidence for unsents existing on the Farplane. Consider Shuyin, or, perhaps more credibly, Jyscal, an unsent who leaves the farplane, though for a very short time.

Next is how the black mage sphere got onto gagazet's peak. When Yu-Yevon realized that Zanarkand was going to be destroyed, he commanded everyone in the city to go to the summit of Gagazet, where Fayth scar was formed to create DZ. But Maechen was not sealed into the scar, so he left the recording he made and begun to travel Spira. Over time, he died, but he forgot both the fact that he was dead, and every spell he knew as a blackmage.

heh, I find this a bit hard to believe, but then there really is no explanation as to why that sphere got there. I havemy own theories, but they're so ludicrous that they's suitable only for poorly written fanfics

That is pretty much what we pieced together. The only plothole that we see is why Maechen in particular was not sealed in fayth scar with the other people of Zanarkand.

Was he still alive when the fayth were made? It is known that there was a final battle against Bevelle on the Calm Lands. Even though he was old, he was a mage, and could've fought, ultimately dying and becoming an unsent. That's my theory at least.

Also, the city in the black mage sphere lookes line DZ is because the city in the sphere is Zanarkand, and DZ is the memories of the people in Fayth scar of the real Zanarkand.

Perhaps the difference between Seymour's recreation and the Black Mage sphere is different district / time of day / unnecessary glorification of the recreation...
