my bad, I think I misunderstood the following line "Leo asked with a glint in his eye as he swept his blade through the air". I will edit as appropriate. 

Also, thank for the clarifications.  I want to assume that while Arn has probably been in service for 18 years (assuming you are put in service at 18) he may not be that high in the Battlemage ranks due to his lack of political finesse. Especially, if they are to be advisors or attachés. 

Finally, does that mean that while attached to an element they are under that commanding officer's command? 

Would they ever get attached to a knight element or only a foot soldier one?
