This MLP papercrat is the Princess Celestia, created by muffinshire. Princess Celestia is a Pegasus unicorn and the co-ruler of Equestria with her younger sister Princess Luna, both of whom are responsible for raising the sun, moon, and stars. She is the mentor of Twilight Sparkle, whom she addresses as her faithful student. She is a recurring character in My Little Pony Friendship is Magic.
Princess Celestia's name comes from the word "celestial", derived from Latin "caelum", meaning "sky" or "heaven". Lauren Faust has made several comments regarding the show on her deviantART comments section, and they sometimes pertain to Princess Celestia. She was originally supposed to be Queen Celestia, the highest authority, with no parents who outrank her. Her status was changed to "princess" at Hasbro's request.
Faust also mentioned that, during the initial casting of the show, Kathleen Barr, Trixie's voice actress, did a "very good" audition for Princess Celestia before Nicole Olivier ultimately got the role.
Princess Celestia is larger than any of the other ponies, with the exception of Night Mare Moon, who is about the same size until she reverts to being Princess Luna. As with other unicorns, a magic glow surrounds both Celestia's horn and objects she is magically affecting. The color of this glow varies: for instance, it is blue in A Bird in the Hoof, orange in The Cutie Mark Chronicles, and white in Griffon the Brush-off. In The Return of Harmony Part 1, it is blue when Celestia opens the door to the vault, but pink when she levitates the empty box the Elements of Harmony are supposed to be in. The glow is yellow in the remastered title sequence introduced with Lesson Zero, as well as in that episode itself and all the second season episodes that follow it. Her tail and mane have a natural flowing motion, even when Celestia herself is not moving.
Princess Celestia acts as a mentor to Twilight Sparkle. She often does not directly state her goals, but rather gives the advice to help her students find the answers they need. For example, she wrote a letter prompting Twilight to make friends in Friendship is Magic, part 1 when her goal was for Twilight Sparkle to find the Elements of Harmony.
Though viewed with great reverence and awe due to her position, she often encourages her subjects to relax with jokes and gentle questions. She also shows great patience with any inappropriate behavior towards her, as seen when Pinkie Pie snatches a cupcake from her at a party in A Bird in the Hoof. Also in the same episode, it is shown that she has a pet phoenix, Philomena.
Princess Celestia displays a fun-loving side when she chuckles at the bottle of disappearing ink sent to her by Twilight in Griffon the Brush Off. In A Bird in the Hoof, while sipping from a constantly refilled cup of tea, she pretends to sip from her already full cup, causing Mr. and Mrs. Cake to overfill it. She is unmoved when Pinkie Pie devours one of the Princess's cupcakes, while the Cakes panic and drag Pinkie away. Celestia tells Twilight and her friends in The Best Night Ever, after they ruin the Grand Galloping Gala, that she always found the Gala awful and she feels they've livened it up.
While kindhearted and slow to anger, Celestia's patience does have its limits. When faced against the threat of Discord's return in The Return of Harmony Part 1, Celestia wastes no time in demanding that Discord return the stolen Elements of Harmony.
Also, in Lesson Zero, when Spike makes her aware that Twilight inadvertently unleashed mass chaos onto Ponyville in her obsessive attempts to find an overdue friendship report to send to the Princess, Celestia personally intervenes to undo Twilight's out-of-control spell. She sternly orders her student to a private meeting to discuss her actions, but remains understanding, and at the insistence of Twilight's friends she agrees not to punish Twilight, instead asking them all to send her friendship reports only when the lessons make themselves apparent to them. In A Canterlot Wedding - Part 1, after Twilight accuses imposter Cadance of being evil, she, along with the others, makes it clear her deep disappointment in her student and walks out on her after Shining Armor and the other ponies. But in A Canterlot Wedding - Part 2, while displaying righteous rage to the newly exposed Queen Chrysalis, she eventually commends Twilight for her instincts that told her the imposter Cadance was evil, thus admitting even she was wrong and apologizing to her for not believing in her at the wedding rehearsal.
In Ponyville Confidential, the Cutie Mark Crusaders manage to get a hold of a photo depicting her eating cake in an unladylike manner for their Foal Free Press gossip column titled "Celestia: Just like us." At the end of MMMystery on the Friendship Express, she admires the cake made by the combined efforts of the bakers and overlooks Pinkie's attempts to gain her attention.
As indicated by her Cutie Mark, Princess Celestia's special talent is raising the sun at dawn and bringing the day. However, while her sister Luna was banished as the corrupted Night Mare Moon, Celestia proved that she is also capable of raising the moon and the stars to bring forth the night.
She has also wielded the Elements of Harmony on two occasions: once together with Princess Luna to petrify Discord, and again to banish Night Mare Moon. However, in The Return of Harmony Part 1, it is stated she is no longer able to do so, and her waning control over the Elements allowed Discord to shatter his prison.
Princess Celestia displays additional powers on the side. She is able to use standard unicorn telekinesis and appears able to teleport. She also seems to be skilled in reversing harmful spells, as per her nature of keeper of Order in Equestria. In The Cutie Mark Chronicles, she is able to easily stop Twilight Sparkle's wild magic burst, and in Lesson Zero, she dispels the Want It Need It spell from a massive amount of affected ponies at once. Albeit she is rarely seen using it, it is probably safe to say that her magic is at least on par with the impressive powers displayed by her sister Luna.
However, Celestia's abilities do have limitations, as displayed in A Canterlot Wedding - Part 2, when she is attacked and counters - and is summarily defeated - by Queen Chrysalis. As a result, Princess Celestia's tiara is knocked off her head. She pleads Twilight Sparkle and her best friends to retrieve the Elements of Harmony.
