Balbal has thirty floors, split three ways: 14 in the Middle World, 7 in the Underworld, 9 in the Sky. The middle two numbers are not invented.
Three realms
The basic structure of Turkic and Altai shamanic telling has three layers: the sky, the middle world and the underworld. What binds them is Ulukayın, the world tree — roots below, trunk in the middle, branches above.
The kam travels along that axis. He descends to look for a sick person's fled soul and climbs to carry a plea upward. The journey itself is a route, and Balbal walks exactly that route.
Why seven below
In Altai telling the underworld has seven layers, each with its own test and its own keeper. Erlik sits at the bottom.
Seven is not accidental in this geography: seven stars (the Great Bear), seven days, seven layers of earth. The shaman's descent is told in seven stops, and at each stop something is left behind.
So Balbal's Underworld is exactly seven floors: Erlik's Gate, The Nine Rivers, Shahmaran's Cave, The Dark Lake, The Iron Tent, The Ghoul Desert, The Eternal Stones.
Why nine above
In the same telling the sky has nine layers. Ülgen sits at the top and the shaman passes nine thresholds on the way up. Some collections push the number as high as seventeen, but the most common and most stable number is nine.
Nine is three squared, and three is already the number of realms. This kind of internal rhyme is common in myth: the numbers refer to each other.
Balbal's Sky realm is nine floors and its last is Tengri's Floor. That floor is nearly empty: white light, a few tiles, one long note. It looks like a design choice but it comes from the telling — the sky empties as it rises.
Why fourteen in the middle
There is no canonical number here. The middle world is not thought of in layers but side by side: where people live is a geography, not a pile.
So the fourteen floors of the Middle World are not a climb but a tour. It begins on the Steppe, enters the Khan's Tent, goes down to the White Lake, passes the Barrows, travels the seasons (Summer Pasture, Winter Camp), stops at the feasts (Nowruz, Hidrellez) and arrives at Otuken.
The fourteenth floor is The Iron Gate — the pass at the edge of the known world and the mouth of the descent. The underworld begins after it.
Why there is no fourth realm
Because there isn't one in the telling. The three realms are a closed system: you go down, you come up, you return. Adding a fourth would not be adding a floor, it would be breaking the shape.
The catalogue can still grow — but sideways, like the Middle World. A new floor means a new place, not a new layer of sky.
