He's a great meat sheild before dropping him off at Cloud Ruler Temple.
I never thought of using him like that

Anyway. In some of my characters' canon, I don't really address the main quest, and only do it just to complete it. For example, my 'Main', is a crime lord. Now why would officials ever come for him for help unless they had absolutely no one else? That is unlikely.
Most of my other characters would count though, and most of them would like Martin.
