Ether (Japanese: エーテル, Ēteru) is an important substance, the building block of all life in the universe of the Xenoblade Chronicles series.
Xenoblade Chronicles
In Xenoblade Chronicles, ether is needed for everything to survive on Bionis, from Zanza to Homs. Ether is the base unit of life and, without it, living beings would not be able to survive. The Bionis itself contains Ether within itself. After living beings of Bionis die, their body is said to "return to the Ether", which the body of the Bionis uses to produce new Ether.
Telethia are able to absorb Ether from their surrounding environments as well as living beings like the High Entia, but that skill was only briefly displayed against Melia and her guards.
Ether can be found in large pools in the Ether Mine and in the Bionis' Interior. It can also be found in Sword Valley and in Galahad Fortress in Mechonis, since the Mechon collect it both in order to weaken Bionis and use it as a lethal weapon against its inhabitants. Liquid Ether is highly dangerous, and rapidly corrodes anything, or anyone, that falls in it. Only very durable beings like Xord are able to survive being submerged, and not without heavy damage.
The Monado is able to manipulate the Ether around it, resulting in the various abilities it grants its user.
Xenoblade Chronicles X
In Xenoblade Chronicles X, ether is a substance discovered by Humans shortly after their arrival to Mira. Due to its recent discovery, most of its properties are still unknown, but several weapons that take advantage of its power, as well as equipment resistant to it, were produced.
Xenoblade Chronicles 2
In Xenoblade Chronicles 2, ether is the main source of energy used by Blades. In battle, Blades absorb the Ether in their surroundings and transfer it to their weapon for their Driver to attack with. However, Blades have a limit on how much Ether can be transferred before their power runs out. When a Blade uses their power, glowing Ether lines can be seen through their body.
Some Blades, like Fan la Norne and Obrona, are able to manipulate Ether, affecting other Blade's abilities.
Ether can also be find flowing through the body of the Titans, similar to blood. The colour of the Ether can be used to identify the condition of the Titan. Genbu's Ether, for example, glow with a pale, blue light, signaling its cold climate.
Ether is also used in order to manufacture several products, like Core Chips.
Xenoblade Chronicles 3
In Xenoblade Chronicles 3, ether is an energy source found from the land. It is harvested from Ether Channels spread across Aionios, and is stored in Ether Cylinders. It is used to power most of the technology found in Aionios, notably Ferronises and Levnises. There exists a higher quality variant of ether known as High Ether, which can only be found from Ether Spheres, and stored in a variant of the Ether Cylinder known as the HD Ether Cylinder+. Its only known use is to power Ino, an Artifical Blade.
Trivia
- In Xenogears, it said that the Zohar Modifier is the source of all ether. Everyone on the planet utilizes the substance.
- In Xenosaga, ether is short for "Especial Theory of Rudimentary". [1]
