The reaction of most folks who have encountered a hor-
ror flit is, “Burn it with fire!” But a handful of naturalists
seek out these creatures for a variety of purposes, paying
handsomely for samples. Bounties for these creatures in
urban areas range from 10 to 100 gp.

Lore

DC 10 Intelligence (Nature): A horror flit has no
eyes, but they sense their prey by means of vibrations in
the air or in the water. They breed by infesting the flesh
of their prey.

DC 15 Intelligence (Arcana): The largest of these
creatures, called “breeders” by most, can spit out swarms
of their young, especially when the breeder instinctively
feels it might die. The creature normally reproduces
more slowly, vomiting a new swarm every few days.

Laethlyn

“Only the desperate would call on the ‘mercy’ of the Laethlyn.
She has none. And if she decides that you’ve committed a
crime against the land she protects, you may suffer a worse
fate than any you were trying to escape.”

Defender of Nature. The Laethlyn, a powerful
fey creature that works outside the politics of the fey
courts, is deeply connected to the natural spaces of
Etharis. They brook no intrusion by those who do not
have those same interests at heart. The Laethlyn tends
to plants and beasts of the wilderness, raising them to
be both companions and defenses against incursions
by the so-called civilized world. They also attempt to
heal those creatures who’ve succumbed to the mutating
powers of the Beast. However, if healing is impossible,
they consider a quick death a mercy and an obligation.
They also see lycanthropes and undead as abominations
that need cleansing off the face of Etharis.

Druidic Knowledge. After generations of walking
the isolated forests of Etharis, the Laethlyn is a source
of much esoteric lore. To those who prove themselves
allies, rather than threats, the Laethlyn could be an
unparalleled source of knowledge and history for druids
and others who want a deeper understanding of the
natural world or the things that endanger it.

Beautiful and Dangerous. The Laethlyn appears
as a lithe elven form with delicate antlers and the light
fur of a deer. Closer examination, however, reveals that
their fur hides strong vines and barbed thorns, which
are devastating when used as weapons.
