Once the lair of Professor Proteus, an old foe of The Cavalier's, Sharpe Island is a small land mass near the mouth of the Thames.  Here an impressive castle/estate was built during the late nineteenth century near the ruins of a small keep.  This estate changed hands over the years until Prof. Proteus inherited it, then turned into a laboratory/base of operations.  The Cavalier fought and defeated Prof. Proteus' minions over the years until there was a final showdown at this island.  Proteus was defeated and sent to prison where he died.

The Island changed hands once again, until finally The Cavalier-now only Brian Griffith-purchased it from the hotel company that attempted to turn it into a small resort.  After a little modification it is now an ideal base for Stormguard.
