Husks makeup about half of the Nightmare population, they very from omega's to ancients in age and power
What a Husk is, is then the nightmare syndrome takes over the Dreamer to fast and the light Eater doesn't have time to copy and leaned from the Dreamers memories and emotions.

This is most common with Force transformation, we're a alpha or ancient uses their Barb chains to infect a Dreamer and force them into becoming a Nightmare.

Fun fact: this is partially why Cataclysm is very immature because Malice try to Force Catch into becoming a Nightmare but was stop before he could finish the job, and then Catch silverblood prevented Catty to continue eating Catch fully. Catty then had time to go over what he had eaten and also with observing he form his own personality but if Malice had continued Catty would have been a Husk instead of what he is now.

When the nightmare syndrome was first placed upon the Dreamer kind, for the ones who didn't die from it there was a 50-50 chance of the Nightmare becoming a Husk, there are more than just the 6 ancient Nightmares but the others are Husks.

Because the light Eater had no time to absorb and learn personality traits and memories before they reached maturity, they are the same as a Farrell Light Eater just with a Nightmare body ( kinda a scary thing) Husks have no personality or intelligent mindset, they only live by instincts, but instead of a light Eater needing Light Magic to survive they crave meat and fear...

Husk travels in packs and can be an assortment of ranks between them.

Intelligent Nightmares generally can use Husks as long as their fed or at least keep from starving, the Husks will follow other Nightmares and can be taught like a dog as long as food is involved.

Some Ancient or Alphas keep and use Husk as others don't bother in keeping Husks around, even though they can have their uses some rather not Gamble with Malice as he can assume control over them.

A Husk can since the Nightmare king and will obey him, even if Mal send them to a certain death they will still do it.

A Nightmares under Malice's control will have glowing green eyes and veins across body.
( Like the Alpha Husk in the pic )

Another thing that makes other Nightmares cautious around them is that Husks are cannibalistic, Nightmares in general are but Husks even more so, if they smell Blood of any kind it drives them into a Feeding Frenzy, some Nightmares use this as a form of entertainment, tossing a wounded rival or anything in a pit with Husks and watch.

Husks do not speak or they do very simple words ( food, meat, more, Etc...) because they just don't have the mental capacity to do so, however they will growl, Roar and make other Sounds.

Husks are also strictly nocturnal then do not like being in day light at all or in bright places.

Most Husks usually stick around dark worlds or the Shadows realm, but will go out and hunt in other words.

It is possible for a Husk to become more intelligent like a normal Nightmare but it would inquire the light Eater to be ripped out as mature light Eaters learn and understand new things better outside their frame, but it would take a lot of work and the know how to do it (call 1-800 Omen for help )

Husks also don't have Forgotten because they likely ate them...

(Ok I think that everything I can think of!)
