Here we go! From Japanese PS 3..
LONG AGO, TWO MOONS, THE "PURPLE MOON" AND THE "BLUE MOON", SHONE IN
THE SKY.
- IF YOU INSTALL THE TWO STONES IN THEIR PANEL, THE TWO FARAWAY MOONS
SHALL RETURN...
- 1,000 YEARS AGO, AT THE TIME OF THE LAIA-ORAKIO WAR, THE TWO STONES
THAT CONTROL THE MOVEMENT OF THE MOONS, THE "MOON STONE" AND THE
"MOON TEAR", WERE REMOVED FROM THE SATELLITE CONTROL SYSTEM ON THE
SECOND FLOOR OF THE WEATHER CONTROL TOWER.
The "Moon Stone" and "Moon Tear" have been gathered together.
Now, if you bring them both to the tower in the desert...
Man above Weapon shop:
- Long ago, one could cross over from this island to the kingdom of
Cille via a shoal that appeared at ebb tide. The shoal stopped
appearing, though, when the two moons moved away.
The location of the legendary Satellite, you ask?
Look up at the sky...
at the twinkling blue moon.
Laia moved it away 1,000 years ago.
But twenty years ago, it was moved back. The blue moon - that's
Satellite.
Siren:
There are yet survivors among the Orakians?!
But I thought my robot armies had wiped them all out!
I am a Siren-type robot!
You comrade Searren is modeled after me.
1,000 years ago, I served Lord Orakio along with the android Miun!
However, Laia used her strange powers to send me away, along with
Satellite!
I've waited 1,000 years' time! My day of vengeance upon Laia is at hand!
(A battle between Siren and the party ensues. Siren is defeated.)
Siren:
Why don't you finish me off?!
Laia's Law forbids killing?
But I'll keep coming back until I die!
Until I have exterminated all the foes of the Lord Orakio to whom I have
pledged my heart!
There. You have the method used. Orakio and Laya took the stones out of the weather tower and the moons drifted away. The moons being moved away disabled transport to the Alisa 3.
When Rhys moved them back in place, Siren and Lune were able to go to Alisa 3.
Orakio took the Power Topaz to Landen and Laya took her stone to access the other fortress/moon away.
1000 years ago, you could go from each moon to the Alisa 3. In this case, Satellite you could go to Flotraan.
Dahlia you could go to Endora(?)
I think Orakio and Laya removed the items on purpose once they learned the error of their ways.
Actually I think Lune and Siren never learned about Dark Force. They resumed the war from where they left off. Lune and Siren do not realize they were duped until Generation 3 when they begin to repent.
In Fact, Wren was modeled after Siren anyways..
Siren never learned about Dark Falz and was continuing his mission. Destroying all foes of Orakio and everything related to Laya.
