Ryshadium are a very large type of horse on Roshar, far superior to any other horseflesh.[1] According to Brandon, there is Investiture involved.


They are thick-hooved[2] and choose their own riders.[3]

Ryshadium are linked to the Knights Radiant in some way.[4] Only a dozen men in all of the warcamps on the Shattered Plains were fortunate enough to ride one.[citation needed]

They can be trained and will obey commands, such as "Away" (making them leave the area) even during the heat of battle. They can bear the weight of a Shardbearer easily and can communicate with them. They barely require 'handlers'.[3]

According to Gavilar, it is rare that they roam far east. Further, Dalinar sees Musicspren trailing after them in the air.[5]

Besides being larger than regular horses, Ryshadium also have a few other unique features. They have stone hooves that are stronger and more durable than a regular horse's hooves, and never need to be trimmed. They also have a large rectangular pupil in the center of each their eyes.[citation needed]


Radiants had Ryshadium, but even kings had little access to ordinary horses.[4]

A man couldn't really understand until he'd had one accept him as a rider. It was like wearing Shardplate, an experience that was completely indescribable.[6]
