I initially took Zmjezhd to be some inflected form of the Russian Змей, dragon, serpent.

The simple explanation for Faldage is that is the right of the lord of the manor to have his tenants pasture their sheep where he tells them to, the purpose being to fertilize the ground with the sheep droppings. That, however, has little to do with why I chose it. It was a name I used before I ever dreamed of having a screen name.
