genprompt_bingo Round 20

It's bingo season! Or, rather, I had finally got around to both completing my Round 18 bingo and posting it to the comm, so obviously I needed a new card, and genprompt_bingo provided me with a lovely one:

Trapped!	Maps	Aliens	Science and Magic	Sentient Weaponry
Books are the Best Weapons	Mystery	When I'm 64: Future	Secrets and Lies	Sun and Stars
Elves, Fairies, Pixies and Brownies	All the Dead Characters are Living Together	Wild Card	Phobias	The Lark Ascending
Falls the Shadow	Reincarnation	Character Death	Mirror, mirror: Doppelgangers, clones and evil doubles	Case / Mission Fic
Hey, it's that guy: Minor characters	Watching Helplessly	Epistolary fic: Emails, letters etc.	Weather	The Oncoming Storm

I had to ask for my free turn in and get a new card (for reasons that were entirely down to me being tired and stupid) but it paid off. I think this might be one of my favourite bingo tables I've been given yet. What to make for it, though...?
