Why Sarregouset?

The Sarregousets or Arragousets were a part of Guernsey folklore mentioned in Victor Hugo's The Toilers of the Sea. The word is probably a corruption of Les Aragousais, 'the men of Aragon', who invaded Guernsey in the fourteenth century, according to The Fabled Coast, by Sophia Kingshill. They were a mysterious, elfin folk who were held responsible for many weird and suspicious events by the reclusive and superstitious populace, and were given strange powers and called by strange names. It is apparent in the novel that they existed only in the imagination of the natives. But as such they are a type or picture of the theme of this work, and most others by Victor Hugo: The misunderstood and anathematized, the untouchables and unreachables, the pathetic and empathetic, the helpless and hopeless, the neglected and broken. I can't say I want to be like the Sarregousets.

Actually, I just happened to be reading this book when I was in need of a unique username.

At night, when it thunders, if you should happen to see men flying in the lurid light of the clouds, or on the rolling waves of the air, these are no other than the Sarregousets.
