There is a castle. It is not distant, because the thing it is away from anything else is not a distance. It is big and grand, cold gray stone on the outside and richly darkly multicolored on the inside, thick red carpets and violet drapes and gold leaf on lanterns and candle-sconces. All of the windows seem to look out over the interior courtyard, no matter what direction they're pointing in.
The interior of the castle is quite well lit, as far as lanterns and candles go, but there are plenty of dark corners and corridors.
This castle has an inhabitant. It might conceivably get it into its head to collect another.
