Controversial issues and their resolutions.

I would like you to consider the following situation. Is it possible for a player to move to an adjacent town without defeating the staggered guard of 20-49 Gr. Fire Mages, in order to defeat another staggered guard of 20-49 Pr. Fire Mages, provided that it was possible to defeat the 20-49 Gr. Fire Mages without leaving the boundaries of their own town? I believe that this is a violation of the rules: it is not allowed to move to an adjacent town without defeating the guard (including a staggered guard). If this is possible, I will also use this opportunity. Thank you!
