Maze with Edison's team

A year ago, a labyrinth appeared, and after 10 months, people from Edison's team began to appear there every week. The first to appear was Grandfather, he was waiting for someone and waited, Hereid, then after another week, Bishka arrived, and Bishka suggested going to the labyrinth and for the first time leaving the camp and the nearby forest into the labyrinth, no one was against it, they spent the whole day there, towards night, the 4 doors of the labyrinth began to close as usual (in the morning they open and at night they close). Hereid and Bishka managed to run into the camp at the last second, but Grandfather did not...
They spent the night near the door in the hope that Grandfather would wait until the morning and come into the camp, but when the doors opened in the morning, Grandfather was already gone. Khereid was worried about Grandfather, Bishka already wanted to cry because there is a very good relationship between him and Grandfather. Grandfather considers Bishka his grandson, and Bishka considers Grandfather as her dead one.
And so a week passed and a new person appeared.
Edison.
He didn't remember anything and didn't know what he was doing in the labyrinth, and had many questions, but only Khereid came out to meet him, and Bishka cried in the camp, then the next week you arrive. You ride in the elevator, it's about a couple more minutes, while you're conscious, but it won't last long.
