Extra Little Character Building Questions

We've now completed character generation for On the Edge of Exile, but we're yet to play the first session (that's next week). The players are still fleshing out their characters, so in that spirit, I wrote a few little questions to help them build backstories that will inform the campaign, and the themes, that we're going to explore.

Also, don't worry, I'll post write-ups of all the characters once they're finished and we get started.

These questions are optional, of course, but they act the same as the Extra Little Worldbuilding Questions, but for player characters, rather than the GM. It's a good idea for GMs to come up with their own pointed (and loaded) questions for their own campaigns, so that they better fit the themes, but I hope my list gives you some inspiration.

1. Who are your parents? Where are they now? Do they know what you are? Do they know where you've been sent? How do they feel about that?
2. Do you have any siblings? Where are they now? Which ones do you remember fondly? Which ones bring up complicated feelings? Anger? Jealousy? Hatred?
3. Who was your best friend? Where are they now? Why aren't they here with you?
4. Who was your worst enemy? What did you do to them to inspire them to follow you? What lengths will they go to to get payback?
5. What dream did you hold, that now slips through your fingers? Is it gone now, forever? What would you do if presented the chance to get it back?
