Here's my theory/prediction of who is Opaline
I believe she used to be a student of Twilight because Opaline has no cutiemark and doesn't know what to do in life. She dreams of becoming the next Princess of Equestria like Twilight. Twilight accepts her after hearing her goals and helps her to get a cutiemark. Another reason why she chose as her personal student because Twilight noticed Opaline's magic is very unique compared to the other students she had.
Things were going very well for Opaline, she learned a lot and made some friends along the way. She became one of the topstudents of the School of Friendships but she never got a cutiemark which was weird because after a big achievement like that. This upset her but she’ll never get up that easily. Her dream became more of an obsession and has an idea of ruling, is by social-like class, meaning a creature with weak magic goes to the low class while the powerful creature goes to the top. Twilight was concerned for Opaline, not her dream of ruling Equestira, her not having a cutiemark yet. Twilight talks with Opaline that she doesn’t need to reach for the stars to achieve everything and how it is best for her to be a teacher, counselor or an advisor. Opaline did not take this well and misunderstand that Twilight is saying that Opaline is not ready be a princess, which shattered her.
Opaline self esteem went low and so pissed what Twilight said “Advisor? me!? Why doesn't Twilight see that I have great potential as a princess, she even says so herself!?” Opaline’s friends try to help her out but said they agree what Twilight and Opaline lashes out on a her who is an earth pony and Opaline said that she a unicorn is better any creature which kinda lend to the discrimination of species. This eventually led to Opaline being expelled. Ending up living in the Everfree forest and plotting revenge. After the incident, things started to go downhill for Twilight and her school. Hate between species and less students come to classes. Luster Dawn became Twilight student after Opaline left, Twilight knew that Opaline will return, so she made the Unity Crystals just in case if anything happens to the magic between creatures or from Opaline. Luster Dawn became the Princess of Guidance and kinda gives a boost to her kingdom, but not for long…
During her exile, Opaline noticed that her power can absorb other magic like a sponge. Then Opaline then using other creatures magic mostly dragon fire makes her power and encourage the discrimination of Equestria for her plan to overthrow Twilight and her achievements
During Luster’s carnation of becoming the next princess of Equestria, Opaline returns and steals Luster wings by using Tirek spell and dragon fire which gives Opaline a cutie mark and being the most powerful alicorn. A great battle happens, Twilight using all of her strength and magic to stop Opaline. Twilight multiple spells she made an invisible-bubble spell, taking all magic into the Unity Crystals and a continental drift which is why the gen 5 map looks completely different from gen 4. Which results in Twilight losing half her powers which she looks different from the message from Make your Mark and losing Equestria hoping if she did the right choice protecting Equestria from Opaline….
