And the winning name?

Orthanc - Black Tower of Isengard 

While perhaps not the most outrageous or controversial, it was by a country mile the most widely suggested and it took some careful consideration to break the tie for second place as there were several good reasons why it's the best name.

Daniel Falconer and Dave Tremont wish to thank all entrants as they thoroughly enjoyed the whittling process.
