>>The Lost, a very old civilization, came back from beyond the grave. They were a big, warrior empire that attacked and destroyed everything at its path. But one day, the Lost were attacked by all the other civilizations at the same time: a trap.
Their city was in the middle of a really deep, humid and dark crater. The enemies used this at their advantage and enclosed them inside it. Giant rocks and lots of deaths were used to make this. But they did not died. Enclosed, they began to use masks: the dust was very toxic. Then, they started to scavenge the destroyed city: little bands were made and they started to kill themselves for food. Until one day... the Miners, (they were neutral Losts that mined and mined the ceiling every hour every day to make an exit) finally reached the light. All the losts joined toghether and walked outside. Light. They could even see a few meters in front of them. Too much light.
With the usage of ancient books that told how the life was outside, they started again. They suceed. They will avenge their dead families.
Character concept, one of all the creeds in a world called Laos. Maybe ill add more information about all this thing later.
