Our company didn't give up on Hans. We are sure he is still discovering but maybe he lost some important communication Items.

Adventurers and Settlers, we would be glad if you find him.
Tell him, that his family is missing him and his daughter just did her Dr. in Physics.

Maybe you can give him the things he needs to come back home.
We know that Hans is smart and strongly believe he will survive. We bet, that he give some hints about where he is going and how to find him for the rescue team.
