The Four Ring Towers

Back onboard the Aselyu, Joshua reunited with the others. Everyone was happy to see him again.
He apologized to them for making them worry so much. But their happy reunion didn't last long. Reports came in that large black globes have appeared at the four towers around the Liberl Kingdom, engulfing the top of each one.
The army had already gone to each location and sealed off the areas.
Knowing that it was the work of Ouroboros, Julia set the ship on course to the nearest tower, Jade Tower.

Estelle's party used the lift to descend down and talked to the soldiers outside the tower entrance.
It seems a man with a mask, wearing white clothes was seen at the top of the tower. Besides the dark globe
surrounding the top, another strange aura surrounded the entrance at the foot of the tower.
Estelle's party was unsure what was going to happen but stepped through.

Inside, they found themselves in a strange place filled with floating crystals and a maze of paths high and low.
It didn't resemble the tower they entered during the Coup De'tat incident. Nevertheless, they had to make their way up. They made their way along the paths, fighting through creatures they've never seen before.
They also found some strange pyramids which projected a worn out message when touched. Joshua guessed they contained records of what happened in the past and so decided to take the crystals that were inside with them. Hopefully, Professor Russell's computer could help decipher them later.

Eventually, they reached the top and there, waiting for them was Blblanc.
Behind him was the strange device they discovered when they explored the tower in one of their earlier adventures.
It was active and a Gospel was set into it, glowing. Estelle's party fought Blblanc and tried to deactivate the device but the Gospel suddenly stopped glowing. The strange barrier around the roof also disappeared.
It seemed whatever Blblanc was doing had been completed. Blblanc once again bowed before them and disappeared.

Estelle's party hurried back to the Aselyu and proceeded to the remaining three towers.
In all three, they experienced the same strange place that they had seen in the Jade Tower as well as find more data crystals from the black pyramids. On the roofs they found Walter, Lucciola and Renne doing the same thing that
Blblanc done. Night had fallen and despite their efforts, Estelle's party couldn't stop them in time.

All of a sudden, the sky grew dark and the sound of thunder could be heard as Estelle's party stood on the Aselyu.
There was a flash of lightning and out of a bright swarm of cloud appeared a giant glowing structure, greater than the
size of Grancel Castle by many times.
Then a burst of energy that resembled that of the Gospel they first discovered, emitted from the structure. In the blink of an eye, all the power in Liberl Kingdom was gone and darkness befell every inch of the land...
