He and Paladin look similar. Both have dark hair, blue eyes, straight nose, strong chin, and a high forehead. Risto's features however are furrowed with stern lines. His haughty expression and cold eyes were unsettling to Kale Allerion and presumably others.
Risto captured a dozen knights loyal to Paladin, including Kemry Allerion, and placed them in an enchanted sleep within Strot's castle-fortress, which he was in control of. Among the captured knights were Sir Joffa, Sir Jilles, and Sir Kemry Allerion.
Lyll Allerion considered him such a great threat she left her daughter, Kale, to be raised by a village of mariones as a slave. She hoped the anonymity would hide Kale from Risto, an effort that was successful.
