>>49438426Cool etymology on Himnasmuga, I wonder if the Heimin fanbase name comes from 'himin' now, that would be a pretty deep cut if it does. I didn't expect the Serafi faction to be subterranean, what with the angel thing. But Sinners being cast down to the bowels of the earth makes sense too, plus there's resonance with the frozen hell concept of Nilfheim/Hel.
Do you know how the cavern system form? Is it Karst topography? (limestone dissolving).
That would be interesting, this kind of process would be extra slow in the polar circle, I wonder if there's such a system IRL.
