"Selen" now? It was "Seren" before.
Is it a reference to anything?
I prefer "Seren" since it is the Welsh word for "star" ... and she seems worthy of such a name.
All hail Best Girl Seren! MEGANE BANZAI!
@SotiCoto Selen is selenium in German, Swedish, and some other languages. Not a bad name, either. Interestingly enough the name of the element comes from an ancient Greek word for Moon (according to Wikipedia). So, no matter of it's Selen or Seren, it's connected to astronomy/heavenly bodies.
