"The caverns here underneath the Sanctuary are illuminated only by dim shafts of light from the sanctuary. The walls are etched with flowers of frost, but at least I am out of the wind. It is warm in one corner here, from the flue that runs under the calefactory. I curl up against the grated opening where the heat eddies. Dark bays line the hall in front of me, a vast rabbit warren, each hold filled to the brim with the scent of the past."
