Pyrkhamen

The name for this world.

The Pyrkhamen is something like a giant stone sponge, where everything is rock up and down. Within this infinite series of rock, there are pockets of Void, which allows for the existance of Ink alongside Moltar, and creates something like an air pocket within the stone.

Far enough away from these pockets, the rock turns to pure moltar. These currents of moltar determine the gravitational orientation of each 'pocket' within the Pyrkhamen, and create the gravitational force.
