Knuckles comes to Twilight Hill after leaving the Frosty Bunker with a quest to retrieve the Chaos Emeralds before Eggman has a chance to. While he finds none in the ruins of Twilight Hill, Knuckles does find an old notebook detailing an explorers journey into the Sunken Palace, and that an Emerald would rest there when reality starts to bend and fall apart.
Sonata lands in Twilight Hill after she escaped the Egg Dreadnought with two of the Chaos Emeralds in tow. She is pursued by Eggmans robots through the ruins until confronted by the Doctor himself on top of a monastery. After crushing the Egg Keeper mech, she manages to hitch a ride with Eggman to the Lunatic Gate.

Once 3 keys have been collected, Knuckles will be directed to climb to another structure further up in the mountains. While Knuckles climbs up, the buildings he is scaling will start to collapse, forcing him to act fast and to dodge any falling debris. The level ends at the entrance to the structure near the top of it.
Twilight Hill is a very uneven landscape, with cliffs and ravines separating larger plains and hills. The ground is very fertile, and has a deep drown colour, though it is mostly covered by emerald green grass. Outcrops of grey stone, man made or natural, are a common sight, as are half destroyed buildings and brick paths. The ravines in particular are rich with plant life, some trees growing large enough for Sonic to climb them.
Twilight Hill receives a disproportionate amount of rainfall compared to nearby areas, and the level is raining during Knuckles and Sonatas levels. When not raining, the area is usually cloudy; seeing little to no sunlight most of the time.
Twilight Hill has a long history of being lost and reclaimed by warring Echidna tribes in it's past, which has led it becoming a dangerous place filled with ancient traps designed to ward off potential invasions. Knuckles level is based predominantly in an area that resembles an old, mostly destroyed village; buried in moss and rubble, hinting at the vicious nature of the conflict.
Some structures in Sonata's version of the stage suggest that at least one of the tribes which populated Twilight Hill believed in some kind of fertility deity, which seems likely given the high amount of rainfall and evidence of farming. It is interesting to note that, among the ruins of Twilight Hill, the statues are left untouched, save for a little rain damage.
A tall monastery is explored by Sonata, and can be seen in the background of Knuckles. It is located high up in the cliffs, isolated from the rest of the village. Numerous modifications, such as Arrow Slits suggest that even religious sanctuaries were unable to escape the pull of conflict.
