A dynasty named "Tianyan" whose civilization is based on traditional ancient customs incorporates the lost mechanical technology called "Cardinal Puppet" developed by the previous dynasty. Thirty years ago, powerful ministers launched a coup, overthrew the "Great Xia Dynasty" who was obsessed with puppetry, and established the "Tianyan Dynasty". They regarded "Cardinal Puppetry" as a taboo art and destroyed it wantonly. However, the technology was not completely lost.
