While most of the sandfalls fall directly onto batches of cacti, one of the sandfalls leads to a normally inaccessible building deep within the district. The bottom level of the district is a maze-like ruin filled with cacti, while the top level is a more open cavern, dotted with numerous sandfalls that connect to the lower level. Near the passage to the Anglerfish Overlook is a small, two-leveled neighbourhood of derelict Nomai houses. Due to the falling sand, a return trip from this district is often impossible. This district serves as the main entrance to The Sunless City from the trail under Escape Pod 2. The second highest district, it leads to a small cavern, the eponymous Anglerfish Overlook, where the player can view and fire a Scout at the Anglerfish Fossil from an opening above it, but is unable to enter its chamber from the overlook. While originally considered safe from the rising sand by the Nomai, erosion has opened up holes for sand to fall into the city, causing it to flood from bottom to top like the rest of the planet, sealing off districts and pathways. The middle of the city contains a lit central hub area built into the cavern wall filled with trees, and a Nomai control panel that switches on lights for each individual district. The city itself is built into a massive vertical cavern, and is divided into four different districts much like the Hanging City located on Brittle Hollow, connected by a network of stairways and gravity lifts: the Anglerfish Overlook District, the Stepping Stone District, the High Energy Lab Trailhead, and the Eye Shrine District. By following written directions left behind by the Nomai in the Crash Site Caves, the player must navigate through a labyrinth of dark tunnels to reach the city. The Sunless City is a large ruined Nomai settlement located deep within the cave systems of Ember Twin. Following other Nomai writings lead to other landmarks in the cave system, including a small grove filled with trees and an opening to the Anglerfish Fossil. Trails of Nomai writing recount their history and mark trails which eventually lead to the Sunless City. The escape pod is embedded into the crust of the planet and creates an opening into the large Crash Site Caves beneath the pod. The second Nomai escape pod can be found near Ember Twin's south pole detailing the events of their arrival on Ember Twin. As sand begins transferring to the planet, the interior caves and tunnels soon become inaccessible, preventing the player from entering the caves or trapping them inside.

The planet has an intricate cave system with multiple entries and sections, which lead to and feature various Nomai structures and artworks. The planet possesses a large canyon encircling its equator running to its core, into which the sand falls from Ash Twin. When the Sun goes supernova and the current cycle ends, all of the sand will have filled the Ember Twin's deep cave systems only a rocky core and a few skeletal stone pillars will remain on the Ash Twin.Įmber Twin is primarily made of red canyons and cliffs, with cacti and various rock formations on the surface. Like an hourglass, all of the sand is on the Ash Twin at first, but then steadily 'falls into' to the Ember Twin over the course of 20 minutes.

Over time, starting one minute into the game, sand will transfer from the sand planet to the rock planet, filling the inner caves, canyons, and crevices (including the ruins) with sand.

As they are relatively small planets, gravity is low compared to Timber Hearth, but not as low as that of the Interloper. The Hourglass Twins are the closest celestial bodies to the Sun (excluding The Interloper at its periapsis and the Sun Station). 4.11 Sunless City - Eye Shrine district.4.10 Sunless City - Anglerfish Overlook district.4.9 Sunless City - Stepping stone district.
