Kasmina is a teacher here at Strixhaven and a planeswalker, seen before only briefly during War of the Spark. Past text outside of stories says: 

```Kasmina is the leader of an ancient, secret order of Planeswalkers, a shadowy cabal with mysterious aims. Her larger goals are unknown, but her recent obsession is recruitment. Her preferred method is to identify what she calls "embers", non-ignited Planeswalkers. She helps these mages to discover their potential, even if it means causing trauma to ignite their spark, and then indoctrinates them in the ways of her order.```

Because of this it's possible she is a villain in the making, but at this point it is unclear. For now she appears, a quiet, intelligent teacher, happy to welcome new students to her alma mater, if somewhat mysterious in her ways.

Kasmina is a planeswalker and one of the main characters of Strixhaven. As she appears in future chapters and stories, you will be asked to reprise the role.
