As The Darkness Spreads.

Maybe Starlight Glimmer knows about Trixie's past, maybe not. Whether she does or not, however, she will protect her friend at all costs.
Twilight tries to trust Trixie, but she fears that maybe the magician isn't who she says she is, whether that is a good thing or not. But her friends are there to help.
Trixie, however, can do nothing but cower as she watches the sky grow into a black void.

Implied Ships: Startrix, Appledash, Twipest, Fluttercord. There may be more mentioned or shown.

Probably going to mostly be speech, but it may change in later chapters.
