The Nahel bond is a symbiotic bond between humans and certain types of spren.

It is a mutually beneficent relationship that gives the spren a stronger presence in the Physical Realm and the ability to think and remember more clearly in that Realm. Presumably, it also grants the person bound to the spren a stronger presence in the Spiritual Realm, allowing her/him to manipulate Stormlight more potently.[1]

The Nahel bond has been known of since the Heraldic Epochs.


They also, when they had settled their rulings in the nature of each bond’s placement, called the name of it the Nahel bond, with regard to its effect upon the souls of those caught in its grip; in this description, each was related to the bonds that drive Roshar itself, ten Surges, named in turn and two for each order; in this light, it can be seen that each order would by necessity share one Surge with each of its neighbor.

Known bondsEdit

Nohadon said that the Nahel bond gave Alakavish (who was presumably bound to a wisdomspren) no more wisdom than a regular man. He also lamented that not all spren are as discerning as honorspren.[3]

More recently, Sylphrena has bonded with Kaladin, who is awakening as a Windrunner. Kaladin was made stronger after saying the First Ideal of the Knights Radiant,[4] though Syl was attracted to him long before this occurred.[5] He was further strengthened after saying the Second and Third Ideals.[6][7]

Pattern bonded with Shallan when she was quite young, and more recently was influential in awakening her as a Lightweaver and becoming a Shardblade when she kills[8][9] and when she unlocks the Oathgate.[10] By the end of Words of Radiance, she has spoken the First Ideal and must now speak only truths.[11][12]

Szeth has no spren, and yet can use Surges. This horrifies Syl. This is because his surges do not come from Honor, as do those of the Radiants.


"Alakavish was a Surgebinder. He should have known better. And yet, the Nahel bond gave him no more wisdom than a regular man. Alas, not all spren are as discerning as honorspren."

–Nohadon, in Dalinar's visions[3]

"They need to be better, old friend. We all do. The responsibility of what we've been given - whether it be the crown or the Nahel bond - needs to make us better."

–Nohadon, in Dalinar's visions[3]


When asked whether an Awakened can form a Nahel bond with a spren on Roshar, Brandon replied, "It depends on the spren."[13]
