I absolutely love those two, their backstory is very well written and their looks really match to their positions in the series.
I just wish that we would know more about them, I mean yeah we saw what happend between them before twilight and her friends came but we never saw what happend in between the time where Luna became more and more hurt and insane.
Thats why I drew this Pic, Luna shattering a glas of wine while looking at her sisters portrait with envy and hate, an act that would suit to a hurt Luna if you ask me. What do you think?
Maybe one day there will be an episode that brings more light into the relationship of those two sisters. “
