Hera

The only living daughter, and heir to the Lestrange name, Cassiopeia-Hera Lestrange the second, had much to live up to because of her name. It was no secret that the Lestrange brothers had trouble producing an heir, but by some miracle, Rodolphus and his wife Bellatrix Lestrange (neè Black), the famed sadistic and most loyal Death Eater, had Cassiopeia in the late summer.

Left in the custody of her aunt, Narcissa Malfoy and her family, she was shielded from the prying eyes of the public. Though she was not often seen, many whispers that came from the back-alleys and the dark corners of the wizarding world knew of her name.

She was to be, the next most deadly, most vicious and most loyal to the Dark Lord.

If only, she listened to Narcissa.
