Lost Memories is set in the realm of Ara, a small cluster of islands amid an endless black sea. When demons are seen roaming the lands, the islands' leaders muster their armies to defend their peoples. But who unleashed the beasts upon the islands? And, if this incursion is as unprecedented as everyone claims, why can no one remember life before the invasion? Ara may once have been a land of rest and tranquility, but was it ever free from grief and mourning?
