Nephera Winchester's life was far from simple, and now that she had exposed Dumbledore's true colors in front of the entire Order, everything was about to get much more complicated.
Unfortunately for her, having her ex-headmaster and the Dark Lord conspiring against her was only one of the many problems she was facing.

Some time ago, she had visited a fortune-teller. Never having been a fan of divination, Nephera simply thought of it as a way to pass the time, the news she received, however, were far from happy.

Loss.
Heartbreak.
Betrayal.

Who would she lose? In the middle of a war, the possibilities were endless, truly. And what did heartbreak mean?Sure, she and Sirius had started out as enemies, but now they were dating, and their relationship was thriving, surely, he wouldn't break up with her. And who would betray the Order? With the Dark Lord growing stronger every passing day, people were growing scared, there was no telling what someone might do to stay alive.

Not to mention, the fortune-teller's words were only the tip of the iceberg when it came to cryptic tales about the future. After a visit to the Fae kingdom and a talk with the High Fae, she found out that her life and its course had been marked in the skies the second it began.

Twenty-one stars fell from the sky the day she was born.
And now, those same stars told the tale of three true lions and two true snakes, who had an imperative role to play in the war.

What did the twenty-one falling stars signify? Nephera raked her brain time and time again to figure it out, but she couldn't. And who were the three true lions and two true snakes? She only had one other friend in Slytherin, Regulus Black, who was serving as her spy on Voldemort's side, but in Gryffindor, she had a lot more than three friends.
