Couldn't sleep, so I amused myself coming up with a zillion prompts that seemed fun:

Epistolary (drabbles in letter form)
First-Line-Last-Line (based on a fun writing challenge I did once: whatever topic or theme is fine, but the first and last sentences must be the same)
Growing Up
Adulthood (since I think we’ve done Childhood, and adulthood is fast approaching for our main trio)
The Way Things Work (explanations for how things/the universe actually work in KH)
Women of KH (because this series deserves recognition for its awesome women in a medium that too often resembles a boys’ club)
Parallels
History Repeats Itself
Lessons Learned
Service
Idealism and Cynicism
Catching A Break
Interludes
Peace and/or War
Legacies (“the measure of a man stands or falls with what he leaves behind”)
Why You Mad (those things in KH that enrage us, examined)
Those Intriguing Moments (the random tidbits that catch our attention, for whatever reason, and make our brains run in circles)
Why We Do What We Do
Spirit(uality)
Rebirth (both literal and figurative)
Your Pet Theory
What They Deserve
Traveling and Exploration
Perseverance
Transitions
Courage
Transcendence of the Human Spirit

Your Favorite Quotation (include with your drabble)
