Two of the Master Keepers of the Ravens, tasked with tending to the flock.
Background
Not much is known about the old couple's background, despite all the stories they tend to tell the young hatchlings.
All that is known is that they were at some point socialites, living free and without worry among the upper class of England, until they realised that the life of an aristocrat wasn't one they wanted to live.
Story goes that they one day up and left their mansion and donated their coffers full of gold to various charities, passing out even their dresses to the poor of England.
After they had given all they could, Luna saw their good deeds, and decided to take them under her wings, marking them as the oldest inductees into the order.
