Here's my own theory, I'll try to be short:

Summer and Cinder were partners at Beacon. Summer had always tried to befriend Cinder but she was more interested in gaining power, though they still worked together quite well. Eventually Cinder learned of a (expressly forbidden) aura-dust technique that would allow someone to control the creatures of Grimm. Ozpin learned of her scheme and ratted her out.

Instead of being imprisoned, Cinder used the powers she had already gained to evade and overpower her pursuers and vanish into obscurity. Cinder also learned of a prophecy that the one who tried to use this technique would ‘fall by the silver eyes’, a trait that she remembered Summer talking about a lot; a family trait that had been absent for over ten generations until she had been born.

Cinder could not allow any chance that someone could interfere with her plans so, by following Summer’s exploits, she learned on a somewhat routine extermination mission that would take place far from public view.

Summer’s skill was more than enough to deal with a pack of adolescent beowolves but what she didn’t expect was to run into her old partner on her way home, nor did she expect said partner to be there to kill her. While both were normally evenly matched, Summer was still fatigued from her mission and travel and was unable to full defend against Cinder’s rage.

Cinder used her influence to cause some surviving beowolves to mess up the place to give the appearance that Summer had fallen while fighting the creatures of Grimm, whom Cinder dispatched after their work was finished, while leaving a brief message that she knew Ozpin would find.

Her dirty work done, Cinder faded away once more, entirely unaware that her once friend and partner had left two young daughters waiting for her at home, the younger of whom had inherited her mother’s silver eyes.

And thus…RWBY
