Anthaos

Most people only get to see an angel once in their lives and when they do it's always this one. The angel of death. After Hexa cuts the string of life, disconnecting the soul from the body, Anthaos is sent to go collect the soul and bring them to the afterlife.
It's the only thing he is responsible for but it is also one of the most important. Without him death can't really happen. Sure people can get hurt but they can't pass on. Hexa can continue to cut strings of life but there really is no purpose because she would just be creating lost souls which isn't benefitial to anyone since they can't worship gods and they can't go into the afterlife to serve gods either.
