Eugenia

Eugenia (full name: Eugenia Chiara LeRoux) was a cis female werewolf in the Lupoverse. She was Jeanne's sister and Eleanora's mother.

Appearance
Eugenia and Jeanne were fraternal twins. As such, they were not identical in appearance. Eugenia had curly black hair, lighter skin than her sister, and amber eyes.

Behavior
Eugenia was deeply resentful that she was born a werewolf and her sister wasn't.

History
When they were very young, Eugenia nearly killed Jeanne many times, until it dawned on her that the best way to get back at her twin was to make her a werewolf too. They were about ten. Shortly afterwards, Eugenia ran away from home.

Some time later, she got pregnant and gave birth to Eleanor. Not long after that, Eugenia reconnected with Jeanne and blah blah blah backstory Jeanne agreed to adopt baby Eleanor.

Then Eugenia was totally weird and then I guess she died?

Trivia

 * Eugenia is one of the few characters in any story who are Really Dead and don't actually appear in the story, just in people talking.
