The Sibling is the powerful spren of the tower, a child of Honor and Cultivation and cousin to Sja-anat. Long thought dead or sleeping, they are nearly corrupted and reduced to an unthinking creature before Navani reaches them through the Rhythm of War. Their bond with Navani awakens them, and together they create Towerlight, restoring the Sibling's agency and renewing the tower's power.
Description
The Sibling is the spren of the tower and is most often perceived through the structure rather than as a separate body. Their presence appears as crystal veins and garnet light within the walls, with a crystal manifestation when they become more directly visible. No humanlike face, body, coloring, or attire is specified; their defining appearance is the tower's luminous, living architecture.
