Littlepips new appearance: [link]
This is what i randomly thought up:
A new war began
The SPP tower was attacked, causing the lightbringer to disconnect from the Single Pony Project module and leave her hanging in midair. Little does she know, she needs to wake up. Because Equestria needs her more than ever.
(The fact that she's upside down underground was to sort of represent that she started her journey underground in the vault, and she'll start underground again)
...Hey, i can dream can't I? XD
(Calamity is probably wondering 'where the hell did she go?')
