Baritone saxophone. It's probably not that underrated or niche, but I don't think it gets enough attention. I really like its range and tone, especially on the lower end, and I've never met a bari who wasn't chill.

Rediscovery of the coelacanth. Probably not my all-time favorite, but I can't think of any others right now. Coelacanths have fossils from up to 410 million years ago but were thought to be exinct since 66 million years ago until 1938 when living coelacanths were found off the coast of South Africa. It's just funny to me that we thought for centuries that this fish was dead and then it just showed up.

Its layout. This might just be "the lore," but I mean seeing the remnants of a civilization and from its structure guessing what it was like before. This is kind of like a combination of traps, puzzles, and statues in the sense that it's about the form and placement of these things. Like is there a massive statue at the front gates or is it small and in a private chamber? Where are the traps located and what were they trying to protect? What kind of traps are they/what did they think they needed protection from? How are the buildings constructed? Is it minimalist and practical or does it have intricate designs? Are there different "districts" with variable levels of quality? Is there organization in layout, and if so, what is at the center verus the outerskirts/what did they think was most important? What are the puzzles even testing in the first place? I find interesting how all these parts come together to show by design (since presumably no one else is around to tell) the innerworkings of a completely different society, so essentially architecture with regards to its purpose.
