Beings
Gartua
Deep in the Maw, there are points where the tunnels open into a place called Gartua. The ceiling gives way to open night sky, and the ground narrows into spans that bridge a void with no visible bottom. Whether Gartua is a location or a single organism is disputed among the .

The Expanse
The expanse is visually overwhelming, and it is not passive. Multiple accounts describe wanderers stepping off the walkway and falling into the abyss without a word. Those who return describe a smell of burnt loam near the thresholds. A traveller without a trained mind and the proper equipment, such as the Hawthorn Wreath, is slowly consumed by what they see.

Mother, offer me your disguise. The wicked deep has many limbs, and many disks from which it sees.
Distance
Distance inside Gartua does not correspond to distance outside. The domain connects parts of the world that should not be reachable from one another.
Order
Despite this, Gartua behaves consistently. Its openings and closings are as predictable as the doors of a house. Under the right conditions, and with a balanced draught of the flower, the thresholds appear in the same positions every time.
Study
The continue to map the system, using the tunnels to travel The Far Country and to study Gartua, in the hope of uncovering its purpose and exact mechanisms.
