Tolb Bell'al was possibly the last Bonecaster of the Ifayle T'lan Imass. His people had long since been thought lost to time by his fellow Imass. Pran Chole last saw him many thousands of years before on the steppes of the Has'erin.
Tolb appeared before Silverfox and had a heartfelt reunion with Pran Chole on the southern coast of Assail. He advised Silverfox that she needed to stop the Kerluhm from continuing to fight the war with the Jaghut.
