Since time immemorial, Nythera has been ruled by blood. Magic is not learned: it is born with each person, and its strength depends on the lineage from which it comes. Dominium Caelestis, the kingdom of the floating islands, maintains the world's balance through its magical currents. As the heir to the ruling family and the brightest magical prodigy of your era, your very existence defines politics, trade, and peace. Will you maintain the balance, or embrace a power that could change the fate of Nythera forever?
