So, I've been toying with a novel idea for a few weeks now and I'm finally deciding to sit down and write it. One problem I've run into early is the naming of the fictional creatures within the story. Obviously, you need some information. The story is based on Earth, but some sort of inter-dimensional entity has plunged the world into literal darkness. This means the sun's light doesn't reach Earth anymore, but its warmth and photosynthetic affects still occur. After all, where's the fun in conquering a planet that died of freezing and starvation? Artificial lights, such as flashlights, still work, but draw the entity's minions like flies to shit, so they're used sparsely (this becomes a huge dilemma for our protagonist and his squad when they're forced to run from one of the creatures and get turned around, not knowing where they are in the city). The issue I'm running into is: What do I call these creatures? The entity takes animals and, sometimes, people that it can get its hands on and mutates them, creating these monstrosities. No one knows what they look like, as anyone who has seen one in light didn't exactly live to tell the tale, but there's tons of rumors circulating. They don't have any specialized vision, so they're just as blind in the dark as people (except for one variant which is introduced later on). Characteristics that are typical amongst them all are sharp claws, jagged razor-like teeth, huge mouths with jaws that can unhinge, and an ear-piercing shriek whenever they see someone, alerting any others nearby.
