A theocratic empire is trying to unite the continent under its banner. Their next target is a small city-state ruled by the protagonist, an Ether researcher. The Empire sends the Dragon Priestess Milia to subjugate the heretic nation, which has eschewed religion in the name of science. Can the protagonist beat back the superior might of the Empire with clever tactics and Ether-based technologies? Or will he finally meet his end by the blade of his former friend, tasked with silencing his heresy once and for all? [From the review on Sanahtlig's Corner]
