This is Reuven and Valst from Obelicta world
Valst used to command a warship. But he fell into enemy hands, was broken, and now he is a mere husk of the man he once was. He is always exhausted, his hands shiver so hard that sometimes he can't move a piece of chess. And tears flow from his eyes even when Valst has enough strength to live and stay awake. However, his minder never complains about the inconvenience.
