The stars have gone… 
Long dormant relics bask in the light of a hundred comets, restoring magics of a previous age. Objects inert for eons become dangers and tools no one can ignore. The use of these artifacts will put everything at risk; all the while providing the greatest opportunity for human advancement in history. 
No matter what happens to the people of Godsland, the dragons have plans of their own.
