Blackmoor Timeline Project

[Havard]

Yep, that's it. There's actually a few such references, and I think that was prolly the first one I came across when I was footnoting that entry. Here is a more biggerer one:

Once, a mighty elven nation (its name
now long lost to the tongues of men) ruled all the North,
and a single grand elven culture spread from sea to sea.
Over many centuries the elves’ power waned, and none
are more cognizant of this fact than the Cumasti, the last
heirs of a great and proud tradition that existed before the
dawn of human history.
Dave Arneson's Blackmoor 2004, Goodman Games.

Indeed! I once made a map detailing Blackmoor's world before the Egg of Coot starts flooding the place with the original Elven Woodlands intact.
