Triangle of Moons: Mending Shards is a My Little Pony: Friendship Is Magic fanfic by Cloud Ring.
Distant, technologically advanced Equestria lives on under another sky that has no sun. Nothing Is the Same Anymore — society, economics, even, to some extent, biology — but many creatures or events are reminiscent of the forgotten past. A disaster — a celestial war of alicorns — is happening for so long that it is mostly normalized. The world remains locked in a rocky stalemate while feuding forces cannot meaningfully manipulate the cosmos against each other's will anymore.
Alicorns are, too, changed by the abyss of time. Still, Twilight Sparkle has some plans in motion. By these plans three heroes are journeying to fix the world that is broken for long enough to forget ever being whole.
Contains examples of:
- After the End: The End had happened many generations ago, so it is not even known about.
- Big Bad: Red Moon, Omnicidal Maniac.
- Cold Equation: A few times; intersects with Vengeance Denied.
- Darker and Edgier: Notably more so than in canon. Death, if offscreen, mutiliation, suffering and all.
- Digitized Hacker: Solid Line, at the end.
- Fantastic Measurement System: No sun means no day, and among three Moons no one could be preferred over the other to designate common days, too.
- Four Is Death: Or at least misfortune.
- Enemy Without: Pink Drop, a synthesis of Gentle Touch and Sharp Cut.
- Logic Bomb: Twice, in different circumstances.
- Magic Knight: Cursory Streak, a strong and bulky pegasus who wields fire magic.
- Mega City: Metropolis, the futuristic city grown over a bigger part of a continent.
- Pre-Insanity Reveal: Red Moon was not always a Omnicidal Maniac.
- Numerological Motif: The world is based on 3 and 9.
- Romance Arc: Gentle Touch and Cursory Streak follow one.
- Technopath: Solid Line, in the latter chapters.
- Split Personality: Plot-driving concept most notable in Pinkie Pie but also many others.
- Teens Are Monsters: In Universe, subverted/explored/exaggerated. Unbounds are teens up to eleven, a full-fledged age distinct both from foalhood and adulthood.
- The Empath: Gentle Touch, projective form of one.
- The Medic: Gentle Touch, again.
- Vengeance Denied: Erasing Red Moon had been an option, probably.
- We Will Have Euthanasia in the Future: Not on screen but it is implied that in this society euthanasia is acceptable.
