Location from The Dresden Files by Jim Butcher
Mab's fortress — an immense citadel of black ice at the heart of Winter, where the Queen of Air and Darkness holds court and the cold is a physical expression of her will.
Arctis Tor is the seat of the Winter Court's power — a fortress of black ice rising from a frozen landscape that stretches to the horizon in every direction. The ice isn't natural. It's Mab's will made solid, and it shifts, grows, and restructures itself according to her moods and needs. Towers rise and fall. Corridors appear and vanish. The architecture is beautiful in the way that a glacier is beautiful — vast, ancient, and completely indifferent to human comfort. The cold at Arctis Tor is not weather. It's a force. Mortal visitors who aren't protected by magic or fae patronage begin dying within minutes — not from hypothermia in the medical sense, but from a cold that attacks the spirit as much as the body. Hope freezes. Warmth becomes a memory. The cold at Arctis Tor is the psychic weight of Winter itself, and it strips away everything that isn't essential to survival. Mab holds court here in a throne room of ice and shadow, attended by the Winter Court's nobles, knights, and servitors. The politics of Winter are brutal, hierarchical, and governed by rules that Mab enforces with absolute authority. Loyalty is demanded. Failure is punished. Creativity in service to Winter's goals is rewarded with power and position. Harry Dresden, as the Winter Knight, has standing at Arctis Tor — which means he has a target on his back and a seat at the table, and it's not always clear which is more dangerous. Arctis Tor has been attacked exactly once in living memory. Someone hit it with Hellfire while Mab was away. She has not forgotten.
Mab's fortress of ice and darkness. Towers of frozen crystal rising from an endless winter landscape. The walls shift and reshape at Mab's will. Beautiful, terrible, and cold in ways that have nothing to do with temperature. The throne room echoes with the screams of the wind.
