I got bored and decided to rewatch the anime and I saw those 'protrusions' at the beginning (The ones that have a kinda conical base), when Klein and Kirito are talking (Just before 5:30 PM), and I couldn't find anything on them (Probably because I couldn't figure out what to search for other than 'conical islands on Floor One'). From what I can see it looked like Klein and Kirito were on one while sitting in the Safe Zone. Does anybody know what those are? I don't recall seeing them further in the anime and I haven't seen anything explaining them. They all seem to have a lake with a quarter moon with an orb (Sun?) between the points floating over it.
