In an unrelated thing except for the sound, one time at a haunted house I helped build, we built a huge towering room we dubbed "The anteroom" The kids, not knowing what the heck "ante" meant, kept calling it the "Octaroom" because it was somewhat similar in sound. The room only had 6 or 7 sides, but whatever. It always gives me a smile to think about it.
I agree all the other bases were themed to fit with lore or something, the octagon sounds silly by comparison.
