This story is a sequel to Kingdom Hearts F.I.M: Days Long Past

Can be read independently of that, however.

Six years have passed since Master Luna took them under her wings in order to teach them how to use the one weapon that may help them save Spike: The Keyblade. Now, after those long years of training, these friends are ready to see new worlds, fight new enemies, and save old friends. Limits will be tested, and bonds will be broken.

Will their friendship be enough to bring Spike out of the Darkness?

Kingdom Hearts based MLP story, no Sora, and no need to have played the games. Characters are human, but those who were pegasi in the show still have magic wings, just as those who were earth and unicorns still have unnatural strength and magic, respectively.
