CLIMATE: Subtropical
TERRAIN: Swamp

The vee of land which narrows to but 30 leagues in
breadth above the neck of the Tilvanot Peninsula is
sunken in the center and cliffed along both coasts.
This cupping causes water to form into standing pools
and sluggish streams and flowages. The resulting
morass of water and vegetation is known as the Vast
Swamp. The upper swamps begin below the middle
of the Hollow and Hestmark Highlands which flank
it to west and east. The swamp runs southward for
well in excess of 200 miles, being over 150 miles
across at the top and funneling down to only 30 miles
breadth at the base where the Spine Ridge rises. The
movement of water in the Vast Swamp indicates that
it gradually drains southward, but there is no known
river rising from the end, so it is thought that there
are underground channels through which the waters
run.

Certain desperate outlaws dwell within the Vast
Swamp, and there are also native humans and humanoid
tribes, bullywugs in particular, found within its
bounds. Ferocious predators and loathsome monsters
likewise consider this their domain. The men of Sunndi,
and the folk dwelling in the hills to either hand,
keep constant watch to assure that these denizens of
the Vast Swamp do not roam beyond its edges. There
are many tales and legends concerning this AREA, but
the most likely is that of the lost burial place of the
demi-lich, Acererak, who once ruled the morass and
beyond into the cockscomb of Tilvanot.
