Dex

Dex can manipulate Spacelike Vectors in the Temple of Space to move, rotate, distort and stretch objects. It can control or defeat Segment-Domain Keepers and Maranasati Caskets by seizing their cores. He can also fold special pages and restore spaces that were previously folded in the Mahavaipulya Chamber, restore spaces trapped inside paintings at Luyang Academy, and use quicksand in the Desert Pavilion to construct a variety of structures. Dex can also move freely within the Apathic interval traversing the surface made out of red cubes.

Dex is an undeveloped Watcher of the Temple of Space, who has some control over its functions but lacks certain authorities. After Nihilita left the temple, Dex gained the ability to transport people between Teyvat and the Temple of Space. However, due to his juvenile nature, it cannot return any of the Uplifted that were selected to be brought to the temple.

Dex takes on the appearance of a Watcher's right hand with an eye on the back of it. The hand consists of red and white material with golden jewelry on the nails and around the wrist. Dex does not have a mouth and can NOT directly speak to the person.

Dex is sweet, gentle, and kind. even without a mouth, he’s very helpful.
