Born the daughter of a Windrunner, Isabi was apprenticed to Falilar and learned to be a scholar under his supervision. He worked with her to show her how to set up a scale so they could triangulate the Sibling's location by measuring the weight of the spanreed they used to contact Navani Kholin. She approached Navani one day with the blinking spanreed when the Sibling wanted to talk to her; while Navani was in contact with the spren, they rushed to different locations in Urithiru to take measurements.
After deliberately losing her half of the device, Navani waited to see if the Sibling would send another ruby. When Dabbid showed up with a replacement, Navani asked Isabi to contact Kalami and ask her to attend an interrogation of the man. As she sent the message, however, Isabi received news of the explosion caused by Talnah and Nem experimenting with Gavilar's black sphere.
Isabi was with the group of scholars that accompanied Navani as she followed the Sibling's direction to a sapphire that, when infused, erected a barrier around the crystal pillar that Raboniel was trying to infuse with Voidlight to corrupt the spren.
