As the both of you were hired as civilians (Neither of you had any rank in the Amstradan army) by the crown of Amstrad, neither of you had any authority over the other, regardless of the respect certain Amstradan government officials have/had for either of you. Sir Roland Goldsteel's nobility is unimportant in Amstrad, since the royal family rules the country centrally, and not through a feudal system.
However, if any of your actions are judged to be against the laws of Amstrad, while actually in service of Amstrad, you can be tried for treason. The penalties of treason are quite severe.
So far however, you have no reason to think you have broken any laws.
[Take, could you write up an NPC for me? (S)he has to be a Xth level something/10th level Weapon Master, at least 40 years old, human, who used to teach you (ie your old master)? You don't become a Weapon Master by visiting inns and taverns, nor even through using your sword a lot, so you need a Teacher. (S)he hence needs a lot of ranks in Profession (teacher) as well. Thank you!]
