Zohar

The Zohar (known as the Conduit in Xenoblade Chronicles 2) is a major reoccuring object in the Xeno-series. Games with detailed explanations of the Zohar typically describe it as having a link to the Upper Domain, thus providing access to an effectively infinite amount of energy from a Lower Domain's perspective. In the Xenoblade Chronicles-series, the Conduit is also used as a gateway to other parallel universes. Although it may vary in name and appearance, different versions of the Zohar have thus far appeared in every Xeno-subseries except for Xenoblade Chronicles X

In Xenogears
The Zohar as it is seen in Xenogears appears as a giant rectangular structure, roughly 30 metres wide and 80 metres tall. Its main body is yellow, and it has a single giant eye which originally housed Kadomony. Rays of texture etched into the body emanate from the eye.

The Zohar serves as the power source of Deus. The Wave Existence is trapped within the Zohar and wishes to escape.

According to Perfect Works, the Zohar has a power to manipulate matter and energy in such a manner to realise any physically possible events in a process called '-phenomenon phase shift-'. Those who can interfere with the Zohar (e.g. Fei) are able to use this (typically subconsciously) to realise their preferred events.

In Xenosaga
In Xenosaga, the Zohar is shaped like a rectangle with two vaguely-triangular protrusions on the sides, forming a sort of cross. Its front features an intricate design, including what appears to be text, surrounding a turquoise jewel-like object in the centre. When the Zohar is activated, lines on its surface glow green and white.

The Zohar was discovered in 20XX at Lake Turkana in Kenya by a group of scientists led by Dr. Masuda.

In Xenoblade Chronicles
In Xenoblade, the Zohar is known as the 'Conduit' (although it is still referred to as 'Zohar' in the game's files). Its form is a giant broad cross, and the entire structure glows with a bright white-green light.

The Conduit was found in Africa at the beginning of the 21th century. It was then studied aboard the Orbital Ring by a large academic institution known as Aoidos, and it was discovered that the Conduit could be used to access parallel universes as well as an infinite amount of energy. The Trinity Processor, consisting of what would later become the Core Crystals of the Aegises, was made to govern and defend the Conduit. The Conduit was used in Klaus's experiment, which resulted in the creation of the universe in which the Bionis and Mechonis reside, but which also led to the almost complete erasure of all current human civilization.

The Conduit is seen towards the end of Xenoblade Chronicles 2 before seemingly disappearing.
