Difference between revisions of "Spanreed"

A '''Spanreed''' is a type of [[Fabrial#Conjoiner| conjoiner fabrial]] developed during the [[War of Reckoning]] that enabled long distance communication on the world of [[Roshar]].{{book ref|b|sa1|c|28}}{{book ref|b|sa1|part=ars}}

Spanreeds, like all conjoiner fabrials, are made by infusing a ruby and splitting it in half. The two halves are then embedded in reed pens. The two pens can then mimic the movements of the other, exactly. The energy required to 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|b|sa1|part=ars}}

The setting of the ruby is able to be rotated to switch between different "modes." One is to alert the possessor of the spanreed's twin that a conversation is desired. Another to alert the first that the message was received. The third and fourth notches sync the movements of the two pens, each notch makes one pen the transmitter and the other the receiver.{{book ref|b|sa1|c|28}}

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|b|sa1|c|28}}{{book ref|b|sa1|c|39}}
