What was Hestia's realm?

Answer 1

The home and the hearth. She was the oldest first born but the youngest last spit out from chronos. She was originally one of the twelve Olympian gods but when dyonisus was born she gave up her tribe to him to avoid conflict. She is basically the warmth of home the one that keeps everything running smoothly in Olympus. She is also the goddess of sacrificial flames so any sacrifice to other gods she gets some of it because the fire is part of her realm. If all the gods were out she'd he the last one keeping the warmth of home ignited. She's like the kind mother figure that makes you feel at home
