Can someone explain Dalamud and Project Meteor and Meteor spell?

[Astrid_Stormborn]

I know Dalamud was a satellite used to bind Bahamut and keep him summoned as an energy source but how did they keep him summoned without Aether?

1. Don't Primals need both Prayers/Faith *AND* crystals/Aether to sustain their form?

2. Also when they try to re-bind Bahamut in a blue field that looks a lot like Dalamud? Dalamud wasn't a magical field it was literally a physical binding.

3. Did the Garleans know if Dalamud had Bahamut in it?

4. Wasn't the project aimed to annihilate Eorzea and purge it of Primals? If so, why drop an elder primal on it(assuming they knew what was inside).

5. At some point Nael tried to cast "Meteor" when the original Dalamud Control System was lost. The lorebook says Meteor (BLM LB3) is a concentrated chunk of crystalized Aether that falls from the sky, resembling an asteroid (hence the name). Is BLM's Meteor different from the Allagan spell, "Meteor"?

6. How/why would the spell meteor drop Dalamud instead of simply calling down a Comet like raid bosses cast it (Thordan EX, Xande, etc). Or was the spell that Nael was trying to cast simply a spell that just magically drew Dalamud to the ground as a fail safe or something? I'm confused...

Dalamud, iirc, was meant to siphon solar energy and direct it to the Crystal Tower to open a voidgate, but failed and caused a Calamity as a result. Assumedly this fire-aspected aether also sustained Bahamut.

1. Aether I already answered, the prayers came from thousands of Meracydian dragons also imprisoned in Dalamud, kept alive but constantly tortured so they'd call Bahamut for help.

2. What Louisoix tried to use was a powerful sealing spell rather than a technological construct. Papalymo uses the same spell at the end of the 3.5 part 1 story.

3 & 4. Probably not. 'Nael' only started the project to use the family's Allagan tech to Meteor Drop Dalamud on Eorzea and wipe out any resistance. Bahamut just took advantage of it.

5 & 6. Supposedly at some point once 'Nael' was tempered by Bahamut, he became a beacon for Dalamud, replacing the Lunar transmitter that had been destroyed by players. Considering that Dalamud was also the world's biggest solar panel (see above), and Bahamut's heart had 1 of the biggest crystals outside of the floating islands of Heavensward, it's not unbelieveable that the spell was the method used (probably granted to 'Nael' by Bahamut, since pure-blood Garleans can't use magic).
