Chivalry

Chivalry is - well, [check the dictionary definition].

Chivalrous ideals (or similar) are found on:

• Larkspur, at least among the few who haven't succumbed to the Undead horde. The Trolls particularly practice their own strange version therof.
• Shade, after a fashion, particularly across Terrimoire. Here chivalry is traditionally directed towards the opposite sex.
