Scrabbling about on numerous insectile legs of various lengths and sizes, these crafty creatures will lie in wait for their victims in a way much like a spider.
In fact, upon entering this world they modeled themselves after spiders in several regards, one of which being a pair of prong-like mandibles that secrete a gluey substance to bind those captured.
It crawls on ceilings, digs through the plasters of walls, and makes nests beneath floors.
While Sirens want to be hidden until the time is right to strike, they also want to be close in order to sense the presence of a meal. Unlike other demons, they must be in close range in order to do this and can’t track by long distances. Strongest senses are hearing and touch.
Their body shape is long and flexible, not unlike a centipede, and they have a hard crusty shell along their backs that protects from attack from the rear. Their heads are spherical, with many pairs of inky black eyes scattered throughout. Their primary colors are muted, making the luminous green and violet flecks on their shell stand out strikingly, appearing to shimmer even in the dark. This might even be because the Sirens have a concept of beauty and consider it a technique in taking hold of their victims.
A few legs in front terminate in opposable clawed hands, which weave expertly around a snared victim, binding them in mucus-covered rope.
This substance has the strength to suspend a full grown human male from the ceiling without danger of snapping it.
Sirens move slowly, their gait jerky and unsure, so catching their victims is a careful task. First they will crawl from their hiding places, sometimes trying to block the exit when no one is looking. When spotted they will speak to the victim telepathically, telling them not to be afraid and trying (unconvincingly) to pose as a friend. Much like the Siren of myth and legend, these monsters rely on persuasion to lure people to their deaths. While most would see through their facade, it’s the unconscious that Sirens manipulate, soothing the pliable beast within and if one is weak enough, “singing” them to sleep.
If this fails to work and if there are no other options, they will attack physically as well as mentally.
Sirens prefer to drag prey off into the darkness, stifling their screams and feeding on them at leisure.
There are not many of them, and they seem to be territorial toward one another and averse to working together.
Sirens also are not prone to running away and will instead venture close, trying to incapacitate anyone they can. One can succeed in “killing” them with a strong enough weapon, but the only thing that seems to pierce their shell is fire.
