Children Of Night

Hello MLP fans I have a new theories for you again. Have you ever herd the song Children Of Night if you have then I have question. Well in the video Luna takes the children to her garden of shadows right. Well what about when Luna got banished to moon what happened to them? Did they die from age,or are they still in the garden or are they in Equestria. I think I know were there they are,well in the beginning of the video the pony said nopony knows we are still here. So that means they are still in the garden of shadow.But how are they still alive? Here my theories maybe Luna might have done a ageing spell on them so they can live longer.
