Myla

 was a commander of a warship. She was the leader of the Last Born. According to Arran she went missing 20 years ago. She was a scientist and her main discovery was to make her race survive a catastrophic solar event. This gave her the name Mother which everyone gave her. She also created the Shift to make her people have bodies that could reproduce, which she knew was a mistake. She created a device which was a birthing chamber which succeeded when Olivan was born. After Olivan was assumed dead, she started to think that she had lived too long. She gave Arran an ultimatum which he rejected. She then got Toban to drive the ship into a destructive radiation stream which destroyed it. (AUDIO: The Age of Endurance)
