Before It All Happened

Long ago in a distant land...

The time before the story. This is where backstories are born and when older characters' flashbacks happened.

The Before It All Happened time period might be constantly abused by Jokes Over Facts in episodic TV shows. For example, it might be shown in varying ways how Guy and Ava got married just so situation-appropriate jokes can be made. But since this isn't canonundefined, who cares about how much the creators alter the marriage? Pterofactyl, that's who.
