This donut shaped plaza wraps around the tower that is The Wayfarers’ Inn.   The plaza itself has a lot of empty space, interspersed with fountains and  stone benches.  A dozen stone pillars rise from the tops of the walls to meet  the tower, about 40 feet up, where it disappears into the  cloudy mists of the sky.  Four great walkways, the wings, head off at right-angles from each other.  Named after the cardinal directions, the North Wing is right opposite the door to The Wayfarers’ Inn.

Perhaps most important are the archways around the perimeter of The Hub.  One leads to the Library Courtyard,  another leads to The Agent's Office, while a third leads to the homes of many adventuring PCs.  Other archways lead to businesses of different types.

The Hub is the beating heart of Netherworld.  People come here to collect their water and get fresh food from the various food carts.   There are even some that sell prepared foods - such as Pumpkin Pie, Cornmeal Porridge and Mushroom Fried Rice.  Others sell Pear Ale, and a more potent brew called Pear Shine.  Note that other dishes are available as well, however they are, almost entirely, plant based.
