Couldn't think of an exciting title, so I pretty much just made a one sentence summary. If you're interested, link here. Description below.

When Starlight Glimmer discovers a locked door in Twilight's castle, she is determined to find out what Twilight is hiding. But Starlight soon discovers that some things are best left hidden. This story was my entry for the Forbidden Knowledge writeoff competition.

Also, if we aren't supposed to post self promotional threads here, just let me know and I'll take it down.
