Machina’s fortress was a jagged, black, iron tower stabbing up from the ground, surrounded by smog and billowing smoke. Huge, sharp and metallic, full of harsh lines and sharp edges, the tower is filled with ramparts covered in thorned metal creepers and jagged shards sticking out from the walls for no apparent reason. A staircase spirals hundreds of feet along the tower walls. At the top of the stairs is a large iron door bearing the insignia of a barbed crown; it leads into an enormous garden. Smooth iron walls surround the garden, topped with jagged spines, and the garden is filled with metal trees and stony paths. At the center of the garden is a water fountain made of clockwork cogs of varying sizes. The clockwork fountain opens a wall, behind which lies the enormous iron throne of King Machina.

The Obsidian Plains

This was Ironhorse’s domain before his heroic death. A massive black plain made of volcanic glass, it is home of Ironhorse’s kin. In the center of the Plains lies the Molten Pool.

The Molten Pool

This pool is a bubbling lake of liquid hot magma at the center of the Obsidian Plains. Close to the Molten Pool, the air is hot enough to peel skin from bone and is infused with the smell of sulfur and brimstone.

Caves of the Packrats

The packrats’ caves run underneath the entire Iron Realm, a maze of tunnels that lead to the boiler room of Machina’s black fortress. The tunnels converge on a giant, cathedral-like cavern filled with mountains of trash, at the center of which sits a throne made entirely of junk. It was from this cavern that Ferrum, the former Iron King, ruled the packrats until Machina’s death.

The Desert of Lost Things

A vast desert filled of sand dunes, the Desert of Lost Things is where all things go that are lost in the mortal world.

Mag Tuiredh

Also known as the Fomorian city, Mag Tuiredh was once the home of an ancient race of giants. Formerly an evil place, full of curses and unknown monsters, it is one of the darkest places in the Nevernever and also the location of the Clockmaker’s tower—the only place in the Nevernever where time is recorded. Everything built there is giant-size, with twenty-foot doorways, streets wide enough to drive a plane through and stairs as high as a normal-size human.

A massive city filled with black towers that belch smoke into a mottled yellow sky, Mag Tuiredh used to sit half in and half out of the mortal realm, in the country of Ireland. Eventually the city was pulled completely into the Nevernever and the Fomorians were driven into the sea, abandoning the city for thousands of years, until it was eventually corrupted by the Iron Realm and became home to the gremlins.
