== Function and Mechanics ==
Spanreeds, like all conjoiner fabrials, are made by capturing a spren inside a ruby and splitting it in half.{{book ref|sa3|100}} The two halves are then embedded in reed pens. The two pens can then mimic the movements of the other, exactly. The energy required for the second pen to move is provided by the holder of the first pen, which feels twice as heavy as an ordinary pen would.{{book ref|sa1|part=ars}} The farther apart spanreeds are, the heavier the pens became after activation. This can be used to triangulate the position of the opposite spanreed.{{book ref|sa4|28}} Furthermore, they cannot communicate faster-than-light, due to a mixture of the fact they grow heavier the further apart they are, and a lag between the communication of two spanreeds, presumably proportional to the distance between them.{{url ref|url=https://www.tiktok.com/@authorbrandonsanderson/video/7153480408280255790|text=Discussion on quantum entanglement|site=Brandon's TikTok|date=2022-10-12}}
The setting of the ruby
Spanreeds cannot be used effectively whilst moving when its pair is stable.{{book ref|sa2|88}} Since the function of fabrials is dependent on the user's frame of reference, a spanreed in motion would be incapable of relaying a clear message to its stationary pair. If both spanreeds are on the same ship, for example, then the spanreed would function properly because both users have the same frame of reference. This is also why spanreeds are unaffected by the planet's motion and curvature.{{book ref|sa3.5|5}}
By the sixth year of the [[War of Reckoning]] spanreeds have achieved widespread use, at least among the [[Vorin]] nations, from the [[Shattered Plains]], to [[Kharbranth]], and even to the isolated estates of [[House Davar]].{{book ref|sa1|28}}{{book ref|sa1|39}}▼
It is possible to create three or more linked spanreeds by breaking a ruby into more than two parts. However, all attempts have currently been unsuccessful.{{wob ref|10750}}
[[Tashikk]] is beginning to become a spanreed hub, with a number of people and places having reeds connected to various businesses in Tashikk. The Tashikk operator is hired by the remote user to exchange messages, to research on your behalf, and to make other enquiries.{{book ref|sa2|24}} ▼
Spanreeds are incapable of interrealmatic communication between the [[Physical Realm|Physical]] and [[Cognitive Realm]]s.{{book ref|sa4|20}}

As of {{rosharan date|1168}}, shortly after the [[War of Reckoning]] began, spanreeds were still regarded as a recent innovation.{{book ref|sa1|44}}
