Miranus is a plane sacred to Miramar, Goddess of Justice. It is composed of a vast and confusing desert, in the centre of which lies a massive temple of Miramar. The sky is caught in an eternal shade of dusk, perpetually standing astride the border between day and night.
It was on Miranus that Miramar was trapped by Prince Slith for a time, though eventually members of Her Order found their way there and managed to strengthen Her by means of the Crystal Decanter, thus allowing Her to shed Her bondage.
