Lions used to live in europe and asia which both have parts in the arctic as well as africa which tends to be very hot. In particular, lions that were in the arctic had thicker fur like the barbary lion in the karma encounters.

So I think it would be nice to have an arctic habitat.

Only lions with thick fur(including decor) and mane(All the manes that are thicker than normal) would be allowed to go to the arctic after x levels. Scars, especially the torn fur would lower the chances of being allowed in the arctic but it wouldn't be impossible. Age will also affect the chances of being allowed in the arctic. Really young lions(0-3 years) and really old lions(10+ years) would both have high chance of getting frostbite and hypothermia.

Frostbite has 4 degrees.

There is first degree frostbite where just warming up gradually is enough to save yourself from getting amputated. This would make the lion a little bit paler. In a RT day or two the lion will be back to normal color. It might become insensitive to cold or heat making it more likely to get burns or frostbite(which is essentially cold burns).

There is second degree frostbite. This causes blistering skin a few days after you get frostbite. The muscles and bone aren't affected at this point. Permanent insensitivity to heat and cold is even more likely with second degree frostbite and it takes much longer(About a month in RT) to get back to normal color.

There is third degree frostbite where the muscles and blood vessels are affected as well as all the skin layers. Bone still isn't affected. A few toes might fall off the lion's paws which would make it deal less damage by grabbing and clawing once the frostbite has healed.

Finally there is fourth degree frostbite. The bone is affected and at its best there is a fracture and at its worst the whole leg comes off. The regeneration herb in my injuries and illness thread would be helpful for third and fourth degree frostbite.

Hypothermia is cold blood temperature. For lions this is below 100 degrees Fahrenheit(37.7 degrees Celsius). This can cause the lion to shiver as it walks meaning it falls more often. It can also cause confusion and at its worst the heart might stop meaning that the lion dies of cardiac arrest.

Both of these are more likely in the arctic but hypothermia is even more likely in arctic waters.

So basically:

Lions of x level and above are allowed in the arctic if they have thick fur and mane.

Factors like achromia and scars affect the chances of being allowed in the arctic.

Frostbite and hypothermia can be aquired in the arctic, even with the thickest fur and mane and melanism(BCS).

Some NPCs that you will encounter in the arctic:

Walrus


A Giant seal with thick skin and blubber. Strength and agility help here.

Orca


The largest species of dolphin. Speed and agility help here.

Polar Bear


The most carnivorous bear on the planet. It is so strong it can catch and kill a walrus.

Shark


An NPC that is encountered in the marsh and waterhole as well.

Arctic fox


A small, white dog that is very fast and agile.

Arctic Wolf


The largest dog that lives in the arctic. Rarely is it ever alone, most of the time it is in packs.

Seal


A mammal built for the water of the arctic. Some seals are very flexible and able to do twists and turns. Others aren't as flexible.

Attack:

You decide to attack her. She quickly takes over and you have some damage done. You walk away slowly because you are hurt. Hypothermia starts kicking in. The blood vessels constrict and the blood on your skin and fur freezes. You have to get out of the arctic now to warm up and heal.

Help:

You help the polar bear cub find its mom. Once you find its mom you tell the polar bear cub to run over to mom.
