New fears for old

What we want is new horrors for the old,
enough of zombies, vampires, or trolls,
there aren't enough of them to fill the holes
that have appeared when it stops being cold.
The ones who want to fight them are so bold
and eager to go out on swift patrols;
they are the ones with well-developed souls,
who've done the job for more than mere gold.
New monsters are now needed, that's the case,
but ones that aren't just squamous or rugose,
monsters that will last beyond this year.
We want some monsters that will set the pace,
that won't be taciturn, nor yet verbose,
but will inspire some deep, gut-clenching fear.
