One More Time...
Each month, someone disappears in the Maria area. These disappearances can't be solved, it's like they vanished into thin air. Eren Jeager disappears this month.
He wakes up in a tunnel, there's a bag in front of him containing clothes, one weapon and a letter.
You are now apart of our game. There are others here, they may kill you or befriend you. You can either work alone or with others. Watch out for traps. Most are deadly. Keep an eye out for chests and bags, they hold supplies. And one more thing, you are never leaving.
