Blood Memory

In July 1978, Lord Voldemort and his new alchemist, Corvus Thorne, planned an experiment devoted to blood purity...
Project "Purity"
Its goal was to "purify" Mudbloods-Muggle-borns-through the use of the blood of certain pure-bloods... thus creating puppets loyal to the Dark Lord.

The project began that same year with two children:
A boy born on January 18, 1978, given to the Lestrange couple.
A girl born on April 21, 1978, given to the Malfoy couple.
They were called Antares and Cassiopeia.

In March 1998, as the wizarding war nears its climax, the consequences of "Purity Project" finally unfold. In the Forest of Dean, Antares sacrifices himself to save Bellatrix Lestrange, dying while believing he had failed her. His death shatters Bellatrix, who realizes too late that she truly loved him despite her ideology.

Meanwhile, Cassiopeia becomes another victim of the war's cruelty. Used as a bargaining piece for her father's failures and trapped in a brutal marriage, she dies before her family can save her. Her death devastates the Malfoys, forcing them to confront the cost of their beliefs.

In the end, the war that promised purity only destroys the very children it created.
