The Dark Mane Society is the Fascist Political party in the 12 Narnian Kingdoms. The DMS' main purpuse is to tack control of the 12 Kingdoms and create A fascist Empire.
The DMS was founded during the Falcarian Civil War. Members of the Garos party we losing many battles in the begining of the War, so some members thought they would cut their loses in Falcaria and plat the Facsist seed in the Narnian Kingdoms. They were opposed by the Narnians in Great numbers, but as the Narnians were a fair people they did not punish the DMS members by death or imprisonment. The Garos werebanished from the Kingdoms. However, while the Garos members were in Narnia they gained a small following who decided to carry on the Garos agenda, though not through war but through politics, in the Royal council. Thus was created the Dark Mane Society. The DMS has always been secretly supported by the Garos party and their Secret police the HKL.

With recent relation break downs with the Falcarians, the Narnian Government is carefully watching the DMS.

The DMS is working in secrecy with the HKL, perhaps for a coup to take over the 12 Kingdoms once again.
