The battle is over, and Cain doesn't want awkward questions, so he follows the map that the chief made for him and darts off into the trees, headed for the hills and the location where the modern city of Hygar is.
The villagers and army patrol will surely be talking about the incident for some time to come, but that's fine, just a bit of amusement for Cain should be need to come back this way.
Once he gets twenty or so Kilometers from the village, where nobody should be able to see him or have followed him, Cain transforms into the Golden Proto Dragon and takes to the sky.
The cliff faces below him are steep and treacherous, and the road leads many hundreds of Kilometers off route, past every significant city in the Empire. Crossing even one of these peaks every few days would be a difficult task on foot, but here, a thousand meters above the valleys and between the peaks, Cain could soar without worries.
