Silili, often derogatorily known as "Horse World" is a planet in its own independent "Silili" system. What seems unique about this planet is the fact that both its Star and moon seem to orbit around one another. Some speculate this effect to be magic, but these claims are commonly dismissed.
Having practically no influence or discussion with the outside universe, Silili seems a very closed off world. Due to this they rarely, if ever, effect the galaxy. Though its sentient and speaking populace of Ponies, Griffins, and Dragons likely have dreams of traveling away from their homeworld. We can only hope that these dreams are brought to fruition before the Jupiter Empire invades.
