Aetherskrivers are devices that allow for the transmission of letters over vast (potentially infinite) distances. They are made using a piece of the coral Syanthazoa that is imbued with a single Wisp, then split in two or more pieces. The resulting pieces are linked across the Loom, and with further enchantment at the hands or gnostic wizards, they will move in concert over a pre-set space.
The pieces of linked coral are attached to a writing arm of an Aetherskriver, which will move when the writing arm of a linked Aetherskriver is moved. By attaching pens or other writing devices to the arms, Aetherskrivers allow the transcription of a letter in one place to result in the immediate transcription of a letter in another.
