Are actually a long-forgotten eldrich cryptid with a cry like death that makes the blood of men run cold in their veins, turns their hearts to stone and their minds to so much dust. Those who come to learn your name learn with it a fear they never knew they could possess. The blind see your horror. The deaf hear your cruel laughter. The ones with no feeling feel your icy talons tracing their spine. The dead tremble and roll in their graves, ever so thankful for the mercy of not having to experience the fear that is you. Soon you will return to this world, and the world will fall to chaos. As fire envelops the world, as all life perishes at your whim, you smile. For humanity should never have forsaken you.
Trying to find the perfect name for a character, but you only have a vague idea of what you want, like “he feels like a 2-syllable kind of guy” or “It need a hard consonant at the end.”
