Level four: hardware, pet supplies
Time moves in a line, but not a straight line. In the Inner Kingdom, time is as hopelessly snarled as a child's scribble. Nomads and refugees from two millenia cross paths, purposes and swords over access to the past, present and future in the trash of a thousand collapsed timelines

Level three: sale items, food court
If the Netherworld is the dustbin of history, it's crawling with roaches. Psychopaths from the future with guns the size of totem poles. Giant firebreathing infants. Deposed sovereign sorcerors. Speed-freak hitmen. Homeless robots.

Level two: real estate, organ donation
Stage a live-ammo war exercise on a recreation of Catherine the Great's beside table, scaled up to a thousand times its actual size. Check out the Inner Kingdom's suspiciously useful jungle, the hotel where the decor is fabulous but the gravity's unreliable, and the forest haunted by the ghosts of every war ever fought.

Level one: the gateway to Hell
Watch out - the Inner Kingdom can turn into a free-fire zone without warning. After all, it's the key to time travel, and time travel is the key to the Secret War.
