Schala clones
When Schala Zeal was lost in the streams of time and fused with Lavos, she sent a clone of herself into the world in an attempt to get help. The clone lived a full and adventurous life, and in the course of normal events, died.
Sometime afterwards, noting the special nature of the clone and the possibilities it presented, Eusic Mori hunted for and discovered the corpse. He devoted a great deal of Atreus' time and money to exploring what secrets might lay within.
