Portal
Hermes glanced surreptitiously at the door in his office that led to a portal that could transport the gods or their young charges anywhere in the world. He felt a bit guilty keeping its existence a secret from the recently arrived heroes, but Hera had insisted.
She was concerned that if they knew about it they would want to use it to come and go instead of staying in New Olympia, which would put them at risk if Cronus found out. Still, Hermes didn't feel quite right about hiding it, not that that was his decision to make of course.
