kinsmanship 

Kinsmanship is a bond shared between two or more individuals. Its more than friendship its more than love its self. There is a closeness, a sense of fearce loyalty to some one not of blood relation. A kinsmanship takes time to be forged, there is a sense of shared trust and honor. Most often its unspoken.

A kinsmanship in its nature is in no way to be taken lightly.

You came blustering in to my life one day years and years ago, how the hell was I to know we were to forge such a kinsmanship. Its stronger than steel, its worth more than diamonds.
