So, just like canon, Summer is dead. She was Ozpin’s apprentice (he… kiiiind of groomed her, NOT IN A SEXUAL WAY TO BE CLEAR).
She was a major optimist, and had a bit of a matyr complex… believing she needed to fix everything and save everyone. This belief only intensified after Ruby’s death. This eventually led to her death…
Fun fact: in my Yang, she has a white bandana. That’s a part of Summer’s cape :)
So… Raven… kind of sucks in my AU.
She loves and is purely dedicated to her tribe. But briefly, she got caught up in the whole Ozpin/ Salem mess, and Ozpin convinced Raven to become the Spring Maiden. After realizing what she was tricked into (aka having a constant target on her back), she retreated back to her tribe.
She eventually popped up again, and her and Tai had a brief relationship, in which Yang was born. She don’t live Tai tho… she just needed an heir, and she believed that Tai was the best fit. When Yang was born, Qrow kidnapped her so that she could have a normal childhood with her dad.
Raven has spent her life trying to track her daughter down… and she finally gets a lead due to the Vytal festival.
When Beacon falls, Raven finally gets her daughter back, taking Yang back to the bandit camp.
