Monk and Robot
A Psalm for the Wild-Built ; A Prayer for the Crown-Shy

It's been centuries since the robots of Panga gained self-awareness and laid down their tools ; centuries since they wandered, en masse, into the wilderness, never to be seen again ; centuries since they faded into myth and urban legend. One day, the life of a tea monk is upended by the arrival of a robot, there to honor the old promise of checking in. The robot cannot go back until the question of "What do people need ? " is answered.
But the answer to that question depends on who you ask, and how. They're going to need to ask it a lot.
