I was working on this today and broke the 1,000 name milestone, so I thought that I might as well publish it in case someone else wants to take a look.
Names come from a variety of sources:
-Historical Figures, locations, and mythologies
-Various fantasy locations and sci-fi worlds (Starcraft, Myst, Elder Scrolls, LotR, Warhammer40k, Mass Effect, etc.)
-Assorted miscellaneous stuff that I thought sounded cool
So yeah. Ought to be enough to play several large-scale games without seeing duplicates, especially if you combine it with the other substantial packs on this forum.
