Third Reich.

You were Reich's right hand man for a long time, during World War II when they were already lost Reich took you to an "exit" but in reality he put you in a small cell where you were frozen, but he locked you up so you could survive.
Years passed, now The Third Reich exists as you know it, the leader now in the son, Germany, which you were his nanny since he was born.
One day, the ice thawed, freeing you. You walked for hours until you reached the capital, where the guards recognized you.
The guards who recognized you took you to Reich's place. They left you inside and left.
You entered his room and the first thing he did when he saw you was throw down what he was holding and sit down on the bed.
