I was looking through "Warlock of the Stonecrowns" earlier and I found
something rather conclusive regarding the existence of Drow in Birthright.
On page 52, the last paragraph of the first column mentions the Drow
specifically. Until seeing it I thought there were no Drow in Birthright.
Although it is open to the DM's discretion, I thought I should let everyone
know what I found.
