Star of Bethlehem

The Star of Bethlehem (ベツレヘムの星) was Fiamma of the Right's flying fortress.

Etymology
The is a celestial object appearing the  of the. Held as a sign of the 's birth, the star leads the to 's birthplace in.

Appearance
The fortress is 40km in radius, with the right side much larger than the others due to Fiamma of the Right being in control.

Principles
The fortress is kept afloat by magical propulsion systems as large as multiple factory buildings, spread out across the four corners of the fortress. The star naturally sucks in all the parts it needs to construct itself and regenerates itself if damaged. It is made of all the holy items from churches and cathedrals around the planet.

As Fiamma of the Right cannot cast normal magic, 200 magicians were borrowed from the Russian Orthodox Church and helped prepare for the construction of this fortress.

Due to the fortress's size, to get between parts of the fortress there are railway tracks and carts carrying people in the fortress. In case of emergencies, on the lowest level of the Star of Bethlehem, there are magical escape containers for the people inside it, which can fly out back to the ground. The escape pods look like buses. and/or telephone booths that are obviously modified in some way.

Purpose
The fortress is a giant ceremonial ground, meant to restore the elemental balance which has been distorted, as part of Fiamma's Project Bethlehem (プロジェクト＝ベツレヘム).

The name of the fortress comes from the star that prophesised the birth of the Son of God - the rise of this fortress is meant to signal a new beginning on Earth. Combined with Fiamma summoning Archangel Gabriel in the form of 'Misha Kruezhev', the sky was transformed into a spell that started a transformation of the planet by purging the world of humans and build 'God's Kingdom' on Earth - giant golden arms (黄金の腕) of Telesma rose out of the ground in response to the signal in the sky that a change is at hand.

World War III Arc
During World War III, the required 'space' and core structure for the Star of Bethlehem was being constructed at a Russian base near the border of the Elizalina Alliance of Independent Nations.

On October 30th, having gathered the necessary elements to enact Project Bethlehem, Fiamma had the Star of Bethlehem take flight, somewhat earlier than anticipated due to the advancing Academy City ground forces. Gathering components from churches around the world, the fortress soon ascended to a height of 3 kilometers. Shortly afterwards, Fiamma summoned Archangel Gabriel in the form of Misha Kreutzev, having the angel changed the sky to a clear night sky and go after the parchments necessary to fill the gaps in his knowledge.

The Star of Bethlehem continued to rise, ascending to a height of 5 kilometers by the time of Fuse Kazakiri's arrival and 7 kilometers around the time Misha unleashed the Sweep against Accelerator, with the fortress sustaining damage from the bombardment but automatically regenerating. Many of the objects in the ceremonial altar used to anchor the angel were destroyed by Kamijou Touma and then the altar itself was damaged by an attack from Fiamma. Having obtained the knowledge he lacked, Fiamma used the Star of Bethlehem to fix the distortion of the four elements in preparation for the next stage of his plan.

As Kamijou Touma faced Fiamma, the fortress had reached an altitude of 10 kilometers. When Fiamma severed Touma's right arm and assimilated Imagine Breaker into the Holy Right, the skies turned gold with Telesma as the area around the Star of Bethlehem was dyed in the colors of Heaven. After Touma regrew his severed arm and as the fight against Fiamma continued, golden arms of Telesma emerged across the world, however their progress was impeded by various individuals. With the output of the Holy Right declining and the heavens dyed with Telesma more than the surface, Fiamma attempted to send the mass of Telesma in the sky down towards the ground in order to regain the advantage, but it was intercepted at an altitude of 8 kilometers by the white-winged Accelerator.

When the power from Fiamma's Holy Right was lost, the Star of Bethlehem was weakened and began to collapse in places, stopping its ascent. Having lost its power source, it started to fall with its speed gradually increasing as its output fell. Remaining on the fortress, Touma destroyed specific ascent spiritual items under Stiyl's instructions in order to influence its direction of travel and descent, guiding it towards the edge of the Arctic Ocean and trying to minimize the damage caused by its eventual impact. When Archangel Gabriel reemerged and headed for the Arctic, Touma changed the fortress's trajectory in order to intercept the angel. Landing on top of Gabriel and the water, the shock of the impact destroyed the Star of Bethlehem.

Homecoming Arc
Around the time of the Radiosonde Castle incident (the object in question being made to resemble the Star of Bethlehem), the recovery and return of the parts of churches and cathedrals from across the world that had been used to construct the Star of Bethlehem was being carried out by religious organizations such as the Roman Catholic Church and the Church of England.

Design Evolution
An early draft of the Star of Bethlehem had it with a more solid and fixed appearance, though since Haimura realized that the structure is continually changing, he gave it a more destroyed and ruined look. Due to the vast scale of the structure, Haimura opted not to put too much detail on the design.
