Pale, hunched, naked humanoids with short legs && long arms,
gibberlings are usually found in desolate woods or dark caverns underground.
The subterranean variety loathe bright light and are particularly afraid of fire.

Forces morale checks: Gibberlings attack in great #numbers#, uttering ghastly howls and insane
chattering noises which cause even the boldest hirelings to check
morale each round, though PCs are not affected.

THACO18: They attack with normal swords and such is their skill in using these
weapons that they strike with a +1 hit probability bonus.

No morale checks: In all circumstances
they will fight to the death, relying on sheer weight of
numbers to defeat their enemies (which means virtually any creature
which dares to venture into their territory, for gibberlings are highly
aggressive).

Though they clearly have a primitive means of communicating among
themselves, they have no discernable language. Curiously, though it
might be expected that creatures who attack in such great numbers
would have leader-types to control them and determine their policy,
no such leader-types have yet been encountered.
Nor are there, apparently, gibberlings of other than the fighter class.
