JW:
I always thought there was a connection between the 150-year-old DD and 
the great dark wizard of 100 years ago.

LV is often called "the greatest dark wizard in 100 years." It would 
appear that both LV and this unnamed wizard overshadowed GW.  I find it 
quite strange that we are never given any other info - not even a name -
 for this villain.  We do not even know how his reputation was earned.

Is this a mystery hidden in plain sight?
