These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Nightmares Are Tragic
Iron Woobie: Princess Luna. She goes mad, is possessed by the Night Shadows, spends a millennium on the Moon while still mostly possessed by the Nightshadows, comes back to find that the One True Love whome she's been hoping for millennia to be reunited has indeed been reborn — as a mare who is completely unaware of her past life — and she is still able to use that knowledge and The Power of Love to help defeat the Night Shadows. And she's still strong, still keeps to her code of honor, and rarely complains to anypony else about her situation. She needs a hug. Lots of hugs.
