“There is . . . a third sibling. They are not with us.”
—Stormfather[1]
The Sibling is a spren related to Urithiru, the Stormfather, and the Nightwatcher.[1][2]
A series of related records left by an Elsecaller in drawer 1-1 of the Urithiru Gem Library associated the Sibling with the health of the tower city. The entries relate the decline of the tower's functionality (particularly with respect to habitation failures) to the withdrawal of the the Sibling.[3][4] The author argues that the spren's disappearance was neither intentional nor a result of internal strife among the Knights Radiant.[3][5] The cause of the Sibling's disappearance is unknown. In the millenia since the abandonment of Urithiru and the Recreance the Sibling has been "slumbering" according to the Stormfather, who refuses to reveal more information because of the way his siblings were harmed by mankind in the past.[1]
“Something is happening to the Sibling. I agree this is true, but the division among the Knights Radiant is not to blame. Our perceived worthiness is a separate issue.”
—The third zircon in drawer 1-1 of the Urithiru Gem Library[5]
The Sibling is likely the third spren associated with the Order of Bondsmiths, given its relationship with Stormfather and the Nightwatcher. It is possible that Melishi was bonded to the Sibling, given the single Bondsmith during the final days of the Knights Radiant tended to remain in Urithiru.[6][7]
