"Atlan?"
Both Atlas and Lilith were taken aback as they heard the demand of the young lady. Just what did she mean she wanted them to free Atlan? Atlas was a Progenitor and was no weaker than Castiel. Why would he need someone to free him?
Moreover, it wasn't as if Castiel and Atlan were close. All those who knew about Progenitors knew that Castiel wasn't close to Atlan or even any other Progenitor for that matter. He always stayed alone since his perception of things was different. In fact, there were even times when Castiel fought the other three Progenitors.
If this girl was clever enough to know their identity, it was evident that she must've known about this enmity as well. So why did she ask Castiel? And what could be the help that Atlan needed? He was so strong that no enemy could hold him back or capture him. No one could even dare, so why?
"Do you know where Atlan is?" Lilith asked. "How do you know that?"
