Miracle Child

Miracle Child is a Homestuck fanfiction by Bramble-Patch. Originally written for the Homestuck Kink Meme, it centers around Gamzee.

The basic set-up is that post-Sgrub Gamzee goes out to the conscription ships, fully expecting to be culled for his sopor slime habit. Thanks to the influence of the Grand Highblood, he is sent to undergo Subjugglator training instead. The fanfic is about how he adapts to sobriety and the violent life of a novitiate. Add in a rebellion in the works led by Karkat, the terrifying personality that is the Grand Highblood, a cast of beautifully written OC classmates, and a truckload of world-building backstory available on the work's Tumblr, and you have the formula for a very good fic.

Find it on the Kink Meme or on AO3. World building, extra characterization, and other such goodies can be found on its Tumblr account.

Tropes used in Miracle Child include:

All in The Manual: There is a lot of world building on that Tumblr. It's not necessary to understand the story, though.
Alternate Universe Fic: Where the trolls were put back on Alternia post-game, some with their in-game powers and all with their memories intact.
Archnemesis Dad: The Grand Highblood toward Gamzee, in a way.
Circus of Fear: Carnival, where the occasional death or bloody merriment is considered normal.
Kick the Dog: The Grand Highblood really didn't need to have Jormun culled, much less order Lazapi to do it.
Mistaken for An Imposter: A digital version. Though considering that Terezi and Karkat thought Gamzee was dead at the time, who can blame them?
Original Character: Surprisingly popular ones at that.
Power Incontinence: Gamzee's lack of control over the chucklevoodoos does not endear him to the other trolls.
Psychic Powers: Gamzee and the other indigobloods can inflict fear on other trolls.
Shoot the Dog: Jormun's death.
The Pen Is Mightier: Lazapi's main strife specibus.
The Messiah: Karkat's brewing rebellion is setting him up as this.
