Unpopular opinion: The pack(s) are treated very well in the ministry.
As much as they get chores to do, it's only to stop them from getting bored.
On top of that, each element of Ghoul or Ghoulette have a different corridor dedicated to their habitational region of the pit, and they're *very* well made.
Water Ghouls: (If running clean water habitat) get a very cool room and a flat rock floor, rounded pebbles in a running stream across the corner of their room and a pond deep enough for them to submerge themselves in, and lots of moss surrounding or in. They don't have beds as they naturally prefer to sleep in water. They can have a sort of like infinity shower that looks like a mini waterfall in the opposite corner too. Basically, lots of water.
For a Tropical Water Ghoul, they like a warm climate and sea or clean water, and so they get about the same set up with a clean water stream, and a saltwater pond with artificial soft waves to mimic the feel of home, and instead of moss and pebbles they get seaweed and sand.
Water Ghouls tend to have their preferences and don't exactly just make do with anything.
For Fire Ghouls: They like a warm, toasty climate, one that would sweat out a Water Ghoul. Their room has heaters in the walls and a ton of insulation, ashy corners from the Fire Elements always lighting something or another on fire, rock floors, and a dug out sort of large hole for them to sleep in. They get heavyweight, fire resistant blankets, and a mandatory sprinkler system because sometimes they have quite a temper.
Fire Ghouls don't change much per region, they like it warm and aren't too picky.
Air Ghouls: they like to have access to light, so unlike their fellow packmates they choose to reside a floor up, where windows are accessible. They love light and wind if course, and want to feel the rain on their skin when they lean out the window. They can get temperamental if they are disallowed access to the outside, which is why they are given balcony's and a mix of easy to take care of plants like basil and mint, and maybe a bird bath or feeder to watch the wildlife.
Earth Ghouls: So. Much. Plant. Everywhere, there's ivy, moss, mint, lilacs, specially sorted of magical plants that only demons can care for, they have hanging plant pots everywhere. There's not a single place in that room you CAN'T have a fresh breath.. But, they really help make herbal medication with their natural green thumb.
Aside from the plants, they have a preference for wood furniture. Wooden framed bed, for most they like bones to decorate the walls, perhaps a closet, and real ivy that creeps up slowly but surely around their room every year, only cut back when it starts to become sentient. Don't ask.
Quintessence Ghouls: Probably the most odd or perhaps normal. Quintessence quite literally just means 'perfection', and the word aether has just.. so many meanings, some greek some odd some scientific. The only thing really known about Quintessence Ghouls is that they *love* the dark. It's their favourite thing, cuddle with them in a dark room and they'll bond with you for life. So, they get utter and complete darkness with the option of a bedside lamp or a ceiling light.
Atleast some of the things known about Quintessence is that they like a cool temperature. They have a metal bedframe, a thin mattress (by choice), light blankets and black coloured everything. They can choose everything they like, but they prefer the simple, quiet and dark.
Multi Ghouls: they get to pick whatever the fuck they like. They change their mind about what they like so often there's practically no point in doing up their room, yet they have plain bedroom with whatever they like as a style, not a habitat. Then, they bounce from packmate to packmate to experience whichever environment their body so desires at the time. They're probably the easiest and hardest to keep all at the same time.
Aside from bedrooms, they don't get anything like lentil slop or stew for dinner every night, they actually get very decent meals usually made by themselves. See, demons can have quiet complicated diets. Water Ghouls are completely pescatarian, Fire Ghouls are somewhat carnivores, who don't need much of the greens at all. Earth Ghouls eat gamey wild meat like rabbit and deer, and *plenty* of their greens. Air Ghouls eat whatever they like really, as they have a flexible diet, but they seem rather keen on fruit. Lots of fruit. Multi Ghouls will inhale everything, even little miss Aurora who will demolish two rotisserie chickens in 15 minutes if given to her. Don't even talk about Swiss, he's just.. Swiss.
And Quintessence Ghouls? They don't have to eat anything if they don't want to. 'Oh, but how is that fair in hell?' you may ask..
Well, in hell they have to fight a LOT more, as their element is prone to violence, which equals an incredible amount of healing. Their Quintessence is healing, and basically drains what we could call a sort of.. reservoir of Quintessence they store in their veins. They regain this Quintessence by eating food, otherwise they don't need to eat.
But because these Quintessence Ghouls obviously don't fight in the overworld, their pack mixed and not many other Quintessence Ghouls to fight with, they just have this never drained reservoir or Quintessence, simply circulating their veins waiting for use.
But sometimes if they notice they're getting too skinny they'll put themselves on a calorie maxxing diet, and then stop eating again.
Quintessence Ghouls are rather confusing.
