Hc about what dead gods where the god of (specially the ones who don’t have confirmation for)
Egeria - god of espionage and sorrow
The girl sends her daughters to spy on people and then either helps those people are messes with them. She’s also known for crying and sorrow
Harvia - salt and salinification
The salt thing is stated however she be literally turned people into salt sooooo
Orobashi - blasphemy and hope
Peorpl always complain and kick him out so why not make that his job. Also having Ei kill the metaphorical representation of Hope means something but right now I can’t think of it.
Deshret - sand and desert
The man live laughs and loves for the desert. Poor Remus never stood a chance against pocket sand.
Nabu malikata - flowers, escapism, and alcohol
I remembering hearing someone come up with this idea and I love it. Her life is marked by sadness so it makes sense she would want to forget that
Boreas - blizzards and wolves 
This makes sense and might already be confirmed. It also makes sense why he is anemo and cryo because that’s how blizzard work
Makoto - transience and cherry blossom
Transience is about the small moments that can’t be persevered a perfect parallel to Ei. Cherry blossom only bloom a few times a year and they slip away fast, also she’s very associated with them
Osial - vortex and waves
Again, no explanation for the first one it’s Cannon. His power involves creating a massive waves to drown people. Maybe rainbows because that’s was mentioned that Rex pierced that in their fight
