Elves say that gates to other worlds lie in
the depths of Weathercote, and that otherworldly
mages of awesome power
have come to Faerun to dwell in the
Wood and guard the gates to prevent others
of their kind from using them. The
truth of this is not known; neither spells
nor psionics are able to penetrate the
Wood?s interior, and those who enter to
investigate do not come out again.

This isolated wood is avoided by all save
the bravest (or most foolish) adventurers; it
has existed since before the fall of Netheril,
persist despite Anauroch?s advance, and
seems to be a place of fell magic. Blue mists
and glowing lights are often seen in its interior
by Zhentarim caravans passing in the
night, to and from Llorkh (q.v.) to the west.
