Trope-a-Day: Blood Brothers / True Companions

Blood Brothers / True Companions: The (semi-) formalized groups of friends, especially in freelance adventurer/weirdseeker/etc. company, known as circles (short for “oath-circles”, because they are; also the second generalized form of Imperial social structure, after the branch).  Not all of them are formalized by oath, however, hence the “semi”, and they come in plenty of variant forms and intensities, ranging all the way up to “for each other’s names and honor, we will kill and die”.
