Arshalia Rei Arcadia (Automaton)

Arshalia Rei Arcadia (not to be confused with the Lord of the same name) is the Automaton of the Ruin Avalon.

Appearance
Arshalia resembles her creator (and to a lesser extent, other members of the Arcadia family), having silver hair and grey eyes. She has two small horns on her head. She also wears a beautiful dress.

Personality
When acting as the Gear Leader of Avalon, Arshalia guides members of the Arcadia family, explaining to them the trials they must complete and answering their questions. She does not react in any way to people not of the Arcadia family.

Background
During the era of the Holy Arcadia Empire, the original Arshalia created an Automaton imitating her appearance, but with a different personality and memories.

During Count Atismata's rebellion against the Old Arcadia Empire, Arshalia performed Baptism on Lux Arcadia to increase his fighting ability (specifically, to increase the time he can spend in Bahamut and allow him to use Over Limit) and hence to ensure that the rebellion would succeed.

Holy Arcadia Empire Arc
Arshalia sends a projection of herself to meet the Drag-Knights of the world alliance at a lower floor of Avalon. She introduces herself, but does not respond to anyone other than members of the Arcadia family. She explains that since there are six possible candidates to obtain Avalon, she will subject them to three trials to determine who is worthy of Avalon. The projection vanishes.

In seven places throughout Avalon, Arshalia uses her multiple clones to subject Lux, Airi Arcadia, Aeril Vi Arcadia, Listelka Rei Arshalia and Hayes Vi Arcadia to the trials. The first trial is to burden the person's mind by showing them the historical execution of criminals by the Holy Arcadia Empire. This ensures that they are capable of withstanding the second trial: Baptism to strengthen the mind and body, allowing them to control Avalon's mechanisms.

At the control room in the centre of Avalon, the real Arshalia is encountered by Lux. She congratulates Lux for completing the first two trials but, before she can give him the last trial, Lux begins fighting with his ally Singlen Shelbrit. After they trade blows, Arshalia warns them that, since they have yet to connect to the centre, they will be removed from the room in five minutes. They fail to finish in time, so Arshalia teleports them out.

Next, Arshalia leaves the control room and appears before Hayes. Hayes touches Arshalia in an attempt to connect to the centre, but fails because she's currently fused with Sacred Eclipse. Fugil kills Hayes and then Listelka undergoes the third trial: having nanomachines poured into her blood, giving her knowledge of Avalon and Sacred Eclipse. However, Fugil decides to betray Listelka and kill her. Arshalia addresses him, revealing that Fugil has also completed the three trials and has previously connected to the centre. Fugil orders her to prepare for a revision of the world, then to teleport him outside so he can deal with the remaining hindrances.

Abilities
Cloning: Arshalia can make clones of her own body using nanomachines. She uses these to oversee the trials in Avalon.

Baptism: Arshalia can Baptise others by injecting Elixir into them using her finger, strengthening them.

Teleportation: Within Avalon, Arshalia can teleport herself and others (presumably by using Avalon's functions).
