After watching her first love, the Good King Sombra from the alternate world absorbing the evil princesses to save the good Princess Celestia. She retired to her private bed chamber at the Canterlot Royal Palace and breaks down. The lost was great to her. After composing herself, Princess Celestia notices her empty diary sitting on her desk. Not since she was a filly has she ever written in her diary. With all her feeling mudded Princess Celestia set quill to paper and wrote till she could not write anymore.
The following morning, a refreshed Princess Celestia raises the sun, as she normally does. After finishing the business of the morning court, Princess Celestia returns to her private bed chamber to rest for a while until afternoon court begins. After a short nap she gets up to write in her diary. It feels good to put all her feeling down on paper. As she opens the cover of the diary, she was shocked to read what she wrote. It has some of the worst things that a hurt and angry mare could write. If any pony finds this Black diary it could hurt her in the long run so she runs down to the Canterlot Archives and hides the Black diary deep in the archives under several out of date maps of Equestria. With the task done, she goes back to work.
Time marches on, the loss of good King Sombra becomes a distant memory for her and good things started to happen. Reuniting with her sister Princess Luna was number one. But something she never thought would happen was falling in love again with a Noble unicorn Knight, Sir Justice Silverlight and marrying him. From that uniting, it bore Princess Celestia three wonderful foals of her own.
Her first born foal, her oldest daughter Princess Aurora Silverlight was a copy of her mother’s personality in the body of a unicorn mare. Her calm manner and natural charm have won over many pony families in her mother’s court.
Her second born foal and only son, Prince Somnus Silverlight was an honorable unicorn knight of unmatched bravery and combat skill, not only with the sword (his aunt’s favorite weapon) but with unicorn magic. He is the unicorn knight that the princess’s count on to aid them when needed.
And finally, her last born foal, her youngest daughter, Princess Blueberry Swirl Silverlight. Her unmatchable compassion have made her a gifted healer and a well loved Royal foal in Equestria along with her older brother and sister.
Now after so many years, the black diary their mother wrote long ago has come to the surface once again. Found by the one pony Princess Celestia was hoping would never find it, her only son Prince Somnus Silverlight. Like his father, Somnus is unquestionably loyal to his mother and would lay down his life to protect her and Equestria. But after reading many portions of the black diary his mother wrote Somnus has started to question his beloved mother’s true intention.
Did she truly love their father, Prince Justice Silverlight and morn him when he passed away?
Does she love her foals like she said she does?
