No one specific thing, but I occasionally would fall down a rabbit hole with lore, or names, or astrology and just get swept up in it. I still enjoy the themes around astrology in its various forms. It's been ages since I looked into it, but I used to find reading about it fascinating. It's funny because I never had any interest in horoscopes, but the descriptions and themes as pertained to the signs and the houses and elements themselves were always kind of neat.
