The Sanctum existed in a part of the palace most people didn't know about.
Not because it was hidden... though it was, behind three locked doors and a corridor that twisted back on itself in ways that suggested either architectural incompetence or deliberate magical alteration... but because those who did know about it had the good sense to never speak of it.
To never acknowledge its existence.
To pretend, when asked, that the Regent Empress Vetra Nivarre had no private chambers deep beneath the palace where the temperature dropped to lethal levels and shadows moved independent of light sources.
Ignorance was survival.
The chamber itself had been carved from a single piece of ancient ice.
