A '''spanreed''' is a type of [[Fabrial#Conjoiner| conjoiner fabrial]] developed sometime before the [[War of Reckoning]] that enabled long distance communication on the world of [[Roshar]].{{book ref|sa1|28}}{{book ref|sa1|part=ars}}
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
The setting of the ruby
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}}
[[Tashikk]] is beginning to become a spanreed hub, with
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}}
