Fae-construct

In blackest night,

Where darkness dwells,

Your dreadful thoughts will weave a spell.

Now run on home!

Don’t be late!

Or True Night’s dawn will seal your fate.

-Valien children’s rhyme  

Fae-constructs, also known as "The Thoughtless", are creatures composed entirely of Fae energy, and born from the wants, desires, and fears of a sentient being. Fae-constructs can be born from any type of Fae, though dark Fae creates them far easier than the other kinds (Sun-Fae does not create them at all). All Fae-constructs are parasitic, and each feeds upon something different in order to sustain its self. New constructs will feed upon simpler, more basic things: flesh, blood, semen, etc. As a construct feeds, it becomes more sophisticated and complex: becoming smarter and stronger, and needing to feed upon ever more complex and abstract aspects of humanity, like hope, fear, sadism, sexual desire, etc. As a construct evolves, it develops ever better traits to allow them to cultivate and feed upon what they require. As a Construct feeds upon a person or people, it will drain an individual of its vitality (in the case of constructs which feed upon more physical things, the individual may literally be consumed) leaving the person a catatonic shell, or just simply dead.
