Valkyrie Eaton, Four's sister joined a new faction after being in Erudite hell yeah she's smart and wise but her father wanted her to reunite with her older brother Tobias aka Four who left them when she was young 5 years ago,

Despite her brother leaving she misses him but at the same time hates him because he had promise to come back for her, to get her somewhere far from their father, Marcus.

So when it was her time to be in a faction she was more than happy, she wanted to be free so Valkyrie thought her path is in Erudite but spending a month there made her realize it wasn't her destiny.

Something else is.
