…Hestia, goddess of hearth and home, by extension light and heat indoors? Even campfires arguably count. Everyone, everywhere, worshipped her. A soldier that marched against her, marched against the force keeping his family warm back home. After a long, tired day of work, a warm fire is enough to elicit heartfelt thanks. Any food that falls into the fire can be taken as an offering. She’s also the oldest and the youngest of the Olympians (born first, nommed first, last out of dad), and that alone carries a ton of power. Only fools would make fun of someone who could claim direct lineage from her.
