Shadows move in the depths, hungry eyes and restless limbs. A sinister world of beauty and terror which swallows those foolish enough to approach it. Oh, the chasm is deep, filled with darkness and nightmares. Go there, if you must – but know that you might never return, my friend.
The game takes place inside a giant, multi-layered chasm. The chasm has swallowed the big cities of the world. Most people don’t know why this has happened, but afterwards, the world started to change: Toxic fumes leaked from the depths and changed the weather for worse. Swarms of strange insects crawled from the murkiness and infested the fields, the orchards and the animals of the people who lived away from the big cities, in villages or as nomads. Nowadays, many have become sick and barely have enough to eat.
Some people have climbed into the chasm in search for answers. They have brought unfamiliar relics from below, some in the language of the city dwellers, some alien and outlandish. They are scientists, treasure hunters, soldiers of fortune. Some want to gain knowledge about this world below, some want the gold they seem certain to find. Some come for the thrill, and some are desperate to end the curse the chasm has cast upon the land.
In time, they (and the player) will learn that the cities were not innocent as to their downfall. Warnings have been ignored, and the underworld has been exploited, thus causing a delicate balance to collapse. The player will gradually find out more about the exact events that led to the world as it is now. The chasm itself is filled with toxic air, which is why adventurers need to plan their trip thoroughly, as no-one can withstand the fumes forever if they want to stay sane and healthy.
