Asirarin

Is the Crown city of the Underworld and is built hanging down from the ceiling as an large stalactite spiraling downward. It is built as an massive fortified Castle that sprawl on, in massive constructs and gigantic hallways and rooms of lavish designs. It is kept by Rathall, they wear white robes and metal masks and moves around the city as white ghosts and are caretakers and servants of Xiara and her city. (Ra meaning Queen and thall Servant ) 

The city itself is heavily fortified and hostile towards any interlopers, that fly to close and will be shoot down or killed by the thousands of statues and gargoyles that guard it.

Only those that have obtained the royal blessing from one of her princesses or princes are welcomed her royal court. Which is the highest honor, and in a city that could house hundred of thousands only a few hundred have access to it and only a few stay within the walls of her crowned city.
