On the world of Panga (apparently a moon orbiting a gas giant), it's been centuries since robots awoke to full consciousness and sapience, laid down their tools, and, after negotiating an agreement with the humans, walked off into the wilderness, never to be seen again.
Now, Sibling Dex, a monk who works as a gardener in their religious house, decides they have had a change of vocation. They now wish to be a tea monk, and travel the towns and villages with a tea wagon, offering tea and comfort to the troubled. This works well for them for a while, till they realize there is still some need unsatisfied. They decide to travel to an old religious house, in what is now the wilderness, long since abandoned. This is more challenging than they anticipated, and this is how they come to meet the robot, Mosscap.
