I found out something amazing....

When Zoe Nightshade died, she became stars.
Zoe is the daughter of Atlas.
Atlas is the son of Iapetus.(aka. Bob)
And...that makes Zoe the granddaughter of Iapetus.
As Iapetus was closing the doors of death. His last words are :
“Tell the stars i say hello.”

AHHHHHHHH THIS EXPLAINS!
