...like attorneys general, or brothers-in-law.
Many have been confused, over the years, on meeting Raven Inkwell, especially those who have business dealings with her, and who travel widely.
Those who frequent the Courts of Canterlot speak of a unicorn with a white coat and dark-brown mane, worn in a bun, whose cutie mark is a quill and inkwell, and who wears round glasses with black frames; the Principal Private Secretary to Princess Celestia, and, along with her Lunar counterpart, the second-most important pony in the Royal Service that administers Equestria behind the scenes, next to only the Cabinet Secretary himself.
Those who travel elsewhere at the right time, on the other hand - or who spend much time in Ponyville, for reasons that are hopefully obvious to anyone versed in recent Equestrian history - speak of a Raven Inkwell who too has a white coat and a dark-brown mane worn in a bun, with the same quill-and-inkwell cutie mark, and the same round glasses, save that this Raven is an earth pony, and turns up all across Equestria where her presence is needed, as one might expect of one of the Royal Service's elite troubleshooters. But very much not as one might expect of the hard-working, ever-busy PPS of the Day Court's princess.
The answer to this conundrum is very simple, and found just over 30 years ago, in the maternity ward of Canterlot General Hospital, where the redoubtable professor Pewter 'Nevermore' Inkwell gave birth to twin foals, identical in almost every respect, after a grueling, multi-hour delivery, and one which involved a lot of missed sleep and rather generous doses of painkillers.
Much to her later embarrassment, she had named both of her daughters "Raven Inkwell" before noticing one's horn, or indeed becoming fully aware that she had produced twins.
Her husband, however, thought it was hilarious.
As, to the confusion of all others, do the Ravens Inkwell.
