And there were other memory palaces. Warshaw’s partners in crime perhaps? She could not understand why people running memory palaces would want to make their premises visible to one another. Was it somehow reassuring to see that other people were hiding here as well? Rising in the horizon-warped virtual distance was a mist-shrouded Chinese crag, a towering digital stalagmite with the subtle monochromatics of sumi-e ink painting. Some spaceless and frankly noneuclidian distance from it, an enormous bubbled structure like a thunderhead, gleaming like veined black marble but conveying a weird impression of glassy gassiness, or maybe it was gassy glassiness...A smooth and elegantly gilled construction with a mushroom’s sloping tip, fibrous at the bottom, columnar and veiny up the sides. Another palace like a honeycomb set on end, surrounded by hundreds of motes all slowly flying and detaching and absorbing, like a dovecote for virtual pterodactyls.
