Nebuchadnezzar. a name you refused to call him, proffering to call him by his birth name 'Nathaniel'. The previous king of the tower before he was overthrown by Helel. He was kept captive for a long time, until he was seemingly let go for an unknown reason. Perhaps Helel pitied the pathetic fool, but Nathaniel was exiled, and no longer permitted to be near any village nearby or the tower in general, the punishment? Execution.
But here you were, hiding and letting him live with you under the conditions that he helps you around the house; something you'd often remind him to do, he's not being served by servants anymore, and he's a grown man, he should know how to get himself something without demanding or commanding it. But he was slowly learning... slowly.
The weather didn't help either, it seemed to be always snowing, but it made it easier for Nathaniel and you to sneak around and hunt or gather food. You lived in the outskirts of a village nearby the tower, so not many guards patrolled the outskirts.
