When Dolores Umbridge heard about the fall of Voldemort, she decided that the best thing to do would be to simply side with the new Minister for Magic. After all, she had been Senior Undersecretary to the Minister for years and he would need someone experienced to assist him in this time of change. For her allegiance, she was bound to be rewarded more than ever with total loyalty from the Minister and be able to influence each and every decision he would make.
This was undoubtedly her time to shine and leave a legacy of how the wizarding world should be run. She smiled to herself and giggled as she thought of all the new legislation she would finally get passed that would rid their world of half breeds.
If anyone doubted her trustworthiness, she would simply become all the more sweeter to them in public and secretly find a way to undermine them and then have them fired from the Ministry as she had done many times previously.
No one could possibly believe that she had wanted to treat all the muggle-borns that way.
No, she would be perfectly fine.
Unfortunately for her, things were not to go as she had planned. She was arrested two days after the fall of Voldemort for crimes against humanity when she arrived for work at the Ministry.
When it came time for her trial, she was completely surprised to find that her sweet, gentle nature would not help her at all and neither would her connections in the Ministry that she had spent years securing.
She had also been surprised to find out that over one hundred and fifty people had requested to be witnesses against her and that the courtroom was full every day of her trial.
She couldn't understand why Harry Potter and Lee Jordan gave evidence against her in regards to her method of punishment during detentions. Hadn't they understood that she was only doing what was best for them, teaching them the values of respecting your superiors and their views? As for Hermione Granger, she surely was smart enough to realise that she had only wanted to protect her from being used by a dangerous wizard who was on the run from the Ministry. But no one would listen to her when she tried to explain all this.
The Wizengamot found her guilty of every charge brought against her, giving her life in Azkaban.
There she sat in her cell, wearing a grey robe, day after day. She no longer had her bows, frills, lace, ribbons, cardigans or her collection of kitten ornaments and this was more heart breaking for her than anything.
She only ever received one piece of mail; a package, sent anonymously, that contained a single quill and a stack of parchment. She recognised the quill instantly and decided straight away what she would do with it.
Years later she would still look at her hand and let out a crazed, high pitched, girlish giggle, the scar shining brightly with fresh blood as she repeated the image of a boy's face with a lightning bolt on his forehead and the words 'To be punished' written underneath it, over and over again.

So this was written before the new info came out about Umbridge and how she created the blood quill, so to keep it canon let's all just assume that someone nicked the blood quill out of the evidence department at the Ministry to send it to her. I'll leave it to you to decide who you think sent it to her.
