The Siren's palace
Before we know it, the carriage pulls up to a halt, jolting us forward with a joint groan of pain, and by that time I realise there is no more stalling. We have arrived.
Peering outside the small carriage window, I vaguely make out a towering crystal palace, glowing with a faint luminescence that just barely manages to illuminate the murky waters around us. Primarily, it is lit by a floating array of sea lanterns that bob and weave in the current, brushing past fish and hurried merfolk and little underwater houses in a flurried array of colourful lights. Beautiful, yet entirely intimidating.
