Okay so for anyone having troubles, I couldn't find him after scouring the island with aura whisper being spammed for 3 rl days:
I found him barely south of Bujold's retreat near the coast. I only finally found him after downloading a mod on nexus that makes him more likely to spawn. I searched for 3 days and then downloaded that mod and found him in 5 minutes. just google filial bonds find torklild.
When I click on him with the command prompt up it says his id is FF0014aa so hopefully that helps someone although i believe the first two characters vary from game to game? not sure though
