❄️: For the downtrodden ones who are shunned by society through no fault of their own but due to their society's bigotry and hatred, we offer refuge. The kingdom is cold, but for them it is safe.

For all others, the winter is a harsh mistress, and they will die of the cold in the endless fields of snow before they can reach those they would harm. That, or torn to pieces by wolves -- it's hard to say what will happen first.

And if an interloper proves to be a problem, we'll trap them and tell them they can be freed once they spell the word "eternity" out of icicles. That puzzle takes them as long as the word choice implies.
