Tyldak was a Glider who had been given the gift of wings. Obsessed with being able to fly rather than merely glide, he begged Winnowill to shape his body to let him soar with the birds. His wings allow him to glide on air currents, augmenting his Glider magic. When Lord Voll learned that Tyldak had Recognized Dewshine, the Lord of the Gliders begged Tyldak to reconsider. He fathered a child, Windkin, but has extremely little contact with him through the years. Tyldak became Kahvi's constant companion. Intensely devoted to her, Tyldak feels that he must protect Kahvi from herself. Although he often tried to dissuade Kahvi, Tyldak supported her in all she did. However, Tyldak stopped short of helping her steal the Egg of Six Spheres from Aurek.
Tyldak was eventually killed by humans in his travels with Kahvi. Kahvi and Windkin split soon after burning his body
