Okay, Greek mythology deep-dive time. When you think 'sea god storms', obviously Poseidon is the big one. But honestly, for battle vibes, I always lean towards his lesser-known sons. Kymopoleia, his daughter, literally called 'the wave-walker', she's a goddess of violent sea storms and gets married to Briareus, a Hecatoncheire—those hundred-handed giants. That's some serious 'wrath of the sea' energy right there. And then there's Phorcys, more of an old sea god, father of monsters like Scylla. He's linked to hidden dangers of the deep, which fits a naval ambush perfectly. They're less about calm dominion and more about that chaotic, ship-shattering fury you'd want in a battle scene. Honestly, makes me wish more fantasy books tapped into them instead of defaulting to Poseidon every single time.
For direct conflict, you can't skip Triton. He's often shown with a conch shell he blows to calm or rage the waters, so he’s got that tactical, battlefield-command aspect. Palaemon too, a young sea god who aids sailors in distress, but that flip side implies he's a witness to those stormy battles. It's the supporting cast that really fleshes out the thematic depth, you know?
