Twelve trees and green suns; refrences to a real world mythology?

[Composer99]

Water as a "recording medium" might also be a reference to the idea of "memory of water", which comes up in Frozen 2, for instance.

I don't know what, it any, folkloric basis the idea has, but it is part and parcel, if memory serves, of the sympathetic-magic-turned-pseudoscience of homeopathy. I daresay the idea didn't originate with homeopathy, though.
