So the question is this, if you have straken and Nork deddog in a unit, which one  will be fighting in a challenge?

Straken has the special rule called "gung ho", where he must always issue and accept a challenge whenever possible. 

Nork has the special rule "loyal to the end" where he must declare a glorius intervention and automatically passes the test. 

Straken is a much better character for challenges and would much prefer him to take them, but the way I read it is that straken must first issue the challenge and then Nork has to fight it for him. 

Thoughts?

Based on what you've provided, Straken must issue/accept if able. Once the challenge has been started, at the start of the next fight sub-phase, Nork jumps in.
