What Entities resemble Balance?

Hello! I'm creating a story with 12 mythological entities taken from existing pantheons and mythologies across the world and am in need of one for balance, specifically one of environmental or physical balance. I already have a deity for harmony and integrity and therefore do not need societal forms of balance such as justice or morality. So something like Themis or Ma'at (suggestions I've had in the past) don't really work. The entity itself does not need to be strictly known for balance either and can be one of its many facets. It also does not need to be from some major established religion and can indeed even be fictional like something from DnD.

For example and further context the being I'm using for harmony is an Alkonost from Slavic folklore. She is depicted as a creature who's very presence brings peace to those near her and is associated with Paradise. So as long as the entity in mind is adjacent to the idea of Balance then feel free to pitch it!

Bonus points if the entity in question has animal counter parts or associations! It can be anything as grandiose as a god or as humble as a spirit btw.

Edit: I have Quetzalcoatl for the cycle of Life and Death and a Peryton for Health and Disease so I don't need that either. I'm thinking more like seasonal/spiritual/Ecosystemic type of balance.

PS: When I say spiritual I'm mostly thinking in terms of like how Iroh explained bending in AtLA.

PSS: for the bot that's looks over posts like this yes I have tried looking on wiki and lists but everything I've seen is tied to things like justice and when I looked at the mythology sub and posted there and a lot of the same was recommend. Ma'at could work if I focused purely on her creation myth portion but I'm hoping to find something a little better. Think about how invasive species destabilize ecosystems or how global warming impacts tempatures and that in turn makes everything spin out of control as the niche's things evolved to fill are either destroyed or changed.
