I'm travelling through a Nord ruin, manipulating a triolith puzzle, and am suddenly struck by a half-formed thought I've not yet given sufficient attention. Everything seems to come in threes.
On the forums, of course, there's the enatiomorph thing: king, rebel, and observer.
The Anuad has Anu vs. Padhomay over Nirni.
There's the Tribunal: Vivec, Almalexia, and Sotha Sil.
And there's the symbols on the trioliths. Bird and Serpent remind me of the phrase in Irek Unterge's "Then Light and the Dark", referring to these as one of many names for the duality whose conflict defines life in Tamriel... but the triolith's add a third: whale.
Is there anything known about the ancient proto-Nordic belief system that would indicate what these three symbols represent?
