Let me tell you the story of Starshield
One night, two griffon slave traders kidnapped Spike in order to sell him. Right when Spike was about to be sold, a mysterious masked pony fought off the creatures there and broke Spike's cage before flying off with him.
When the two of them arrived at the pony's giant home in the middle of the enchanted forest, where plants are alive and, just like all the animals, are very friendly to creatures.
The pony then helps Spike by treating his injuries and giving him food and water. When asked who the pony was, she revealed herself as AU alicorn Starlight. This Starlight was really named Starshield, and came from a different universe, and from the far far far far future. In her universe, she was seen as a criminal by the tyrant ruler Frosted Ice, who forced the entire planet to serve her and killed whoever refused.
But she had been secretly studying about a way to escape, and discovered the existance of another world. So she constructed a portal to come to this world, not knowing which time period she would arrive in, burned the plans and papers to the point that they wouldn't be revivable, and set a timer to destroy the portal 10 seconds after she went through.
And after hearing Spike's side of the story, how he was always picked on, used only for work, and never invited to parties or other special events, Starshield offered to allow him to live with her, and Spike, after thinking for 2 hours, accepted.
