Anyway my personal headcanon after the discussion is that, as elves are beings of nature, each subspecies governs a different aspect of nature. Wood Elves are tasked with protecting the beautiful parts of nature, the flowers and the deer, while the Drow are charged with protecting the repellent parts, the scavengers and the vermin. They're not evil- cockroaches are just as important to the ecosystem as butterflies, and the majestic lion is far more dangerous then any venomous scuttling thing. But alas, it's easy to assume about the figure who speaks for the spiders and the mould.
High Elves, for their part, are tasked with guiding domesticated nature, protecting nature as it intertwines with civilization, which is why they live in cities and work to interact with the other species.
