MERROW
Merrow haunt coastal waters, preying on fisherfolk,
merfolk, and any other edible creature that crosses their
path. These savage monsters snatch and devour unwary
prey, hauling drowned corpses back to their underwater
grottoes to feed.
Transformed Merfolk. Long ago, a tribe of merfolk
found an idol of Demogorgon at the bottom of the sea.
Not knowing what it was, they brought the artifact
to their king. Everyone who touched the idol became
afflicted with madness, including the king, who decreed
that a sacrificial ritual be performed to open a gateway
to the Abyss. The ocean turned red with the blood of
slaughtered merfolk, but the ritual worked, and the
king led the survivors through the underwater gate
to Demogorgon's layer of the Abyss. The merfolk
remained there for generations, fighting for their lives
as the Abyss warped them completely, transforming
them into hulking, evil monstrosities. Thus, the first
merrow were born.
Coastal Bullies. Whenever an opportunity presents
itself, the Prince of Demons sends merrow back to
the Material Plane to wreak havoc in the oceans. The
merrow are bullies, attacking all creatures smaller and
weaker than themselves.
Merrow dwell in undersea caves filled with treasures
and trophies, taken from their victims and sunken
ships. They tie the rotting corpses of dead enemies and
drowned sailors to strands of kelp to mark the borders
of their territory.
