Star Swirl the Bearded

Star Swirl the Bearded is a character first mentioned by Twilight Sparkle in Luna Eclipsed as "the most important conjurer of the pre-classical era." Twilight and her friends visit a wing in the Canterlot Library named after him, which houses time-related spells, in the episode It's About Time.

Development and name
M.A. Larson, the writer of Luna Eclipsed, It's About Time, and Magical Mystery Cure, selected the name Star Swirl out of a list of pre-approved locations and names by Hasbro, then added "the Bearded" because it didn't sound "quite old enough". Larson stated that Twilight Sparkle "would be the kind who'd idolize the great minds of the past." The name Star Swirl was given by Hasbro to several Earth pony mares in toy lines of previous My Little Pony generations, and has been used in Friendship is Magic 's corresponding toy line for another Earth pony mare. A printable Twilight Sparkle paper cutout on The Hub's website, a post by The Hub's Facebook page, closed captions for Luna Eclipsed on the official HasbroEpisodes YouTube channel, different closed captions for Luna Eclipsed and closed captions for It's About Time both on the DVD My Little Pony Friendship is Magic: Adventures in the Crystal Empire, closed captions for Magical Mystery Cure on the DVD My Little Pony Friendship is Magic: Princess Twilight Sparkle, and a post by Wired 's Underwire blog have spelled it "Star Swirl" as this toy line has,   though Meghan McCarthy and Larson (both on Twitter) and The Hub's Facebook app Ponyscopes have spelled it "Starswirl";  Enterplay's trading cards have used both spellings.

Depiction in the series
Star Swirl the Bearded is first mentioned by Twilight in Luna Eclipsed when she explains her costume to Spike. She calls Star Swirl "the father of the amniomorphic spell", "the most important conjurer of the pre-classical era", and adds "he created more than 200 spells! He even has a shelf in the Canterlot library of magic named after him." Later in the episode, Princess Luna recognizes Twilight's costume as Star Swirl and compliments her for it, stating she "even got the bells right," but other ponies that Twilight asks about her costume guess that she's a "weird clown" or a "country music singer". In Dragon Quest, a photo shows Twilight wearing the costume.

According to the pageant staged in Hearth's Warming Eve, Star Swirl was the mentor of Clover the Clever, one of the founders of Equestria. In It's About Time, Twilight searches for time spells in a wing of the Canterlot library that is named after Star Swirl. Twilight says it's "the most secure section of the archives", and needs to be let into the section by one of the guards patrolling the library.

At the end of The Crystal Empire - Part 2, Princess Luna summons a spiral-bound book that has a dark cover which shows two stars and a swirly pattern. In Magical Mystery Cure, a flashback shows the book having been mailed to Twilight in a package with a letter from Princess Celestia. The letter states that the last page of the book contains Star Swirl's "secret unfinished masterpiece", an abandoned spell which he was never able to get right. When Twilight finally fixes the spell Princess Celestia states that Twilight accomplished what even Star Swirl could not, because he did not understand friendship like Twilight does.

Merchandise
Hasbro uses the name Star Swirl for an Earth pony mare with a powder-blue coat and a light purple and pink mane. Both toys of Star Swirl have only been released outside of the United States: the Playful Ponies version packaged with Rarity in the special edition of the Royal Gem Carriage vehicle set, and the mini-figure version as part of the second wave of mystery packs. According to the collector card included with the mystery pack toy, Star Swirl "always sparkles!" In the My Little Pony First Look and Find book, Star Swirl appears as one of the guests attending the wedding of Shining Armor and Princess Cadance.

Series 2 of Enterplay's trading cards includes Equestrian Magic cards featuring "Starswirl the Bearded's Book" and "Starswirl's Time Travel Spell", card #56. The back of card #56 includes the description "ONLY STARSWIRL THE BEARDED has ever whipped up magic strong enough to send a pony back in time! But, even his magic has limits. A pony can only use the spell once, and then only for a few moments. As Twilight Sparkle learned, using Starswirl's Time Travel Spell to warn the past about the future can have drastic results, so one should be very careful casting this spell! Maybe she should have gone back in time to warn Past Spike about Future Spike's tummy ache instead? Nah..."

WeLoveFine sells an art print with a fan-design of Star Swirl the Bearded and a T-shirt showing Twilight Sparkle dressed up as Star Swirl the Bearded.

Promotional material
In The Hub's Facebook app Ponyscopes, of the horoscopes for January 8th, 2013, attributed to Twilight Sparkle, the Sagittarius horoscope is "It's time to restock supplies! I always carry extra quills, scrolls, ink, books, and Starswirl the Bearded's tenants at all times."

In Hot Topic and The Hub's Hot Minute interview with Twilight Sparkle, she responds to the prompt "Favorite hobby" with the answer "Spending time with my friends. And this pony can never read enough about the bold and brilliant Star Swirl the Bearded."
