Since Riot's doing updated lores and making new short stories for Champions

I would like to know a bit more about Syndra. Namely, these four questions.

1. Was she an orphan like Zed, or did she have a family?
2. How did she mentally develop as a child?
3. What did she do with her magic to scare her village elders that badly?
4. What about her relationship with her master? Was he a lenient father-figure, or a strict instructor?
