Greetings
The values and beliefs of the High Elves could revolve around a society based on arcane magic, knowledge and politics, something like a magecracy.
However, the further you move away from the larger urban centers, the High Elves could be beings closer to nature and the divinities related to it.
In this way, the values and beliefs of the High Elves of this post could be linked with their architecture that we saw in the previous one.
See you.
