The cylindrical map is supposed to approximate the sphere by claiming that the poles are too hostile for anyone to travel. Remember also that distance = speed x time, so assuming that it's harder to travel on colder climates than warmer ones, the "enlarged" areas are actually accurately represented, and units just take longer to travel. Of course we are imagining large ice caps here, not the ones on Earth that are about to disappear in 10 years. Why are large ice caps so hard to imagine anyway? This is the end of the age of ice!
Torodial maps can be donut, they can also be spherical, albeit with "distorted" dimensions as usual. Either way, I STILL cannot accept that Erebus is flat. I can't imagine a flat world, nor could I imagine Bhall falling through the ground into hell. There is also another problem though.
When the Bannor were in Hell, there weren't really humans, but rather souls, without flesh, but with souls that can be injured, captured and tortured again. But they can't be "killed", because they're already "dead". Perhaps this need clarification: once a human enters hell, the flesh becomes "shade-nature", the very physical nature of everything changes. Once you enter a portal back to the mortal realm, you become "substantial" again, and then you can be killed just like normal. If my interpretation is correct, Bhall could not have literally fell through the ground into hell, for that would imply that hell and Erebus have the same "nature of existance" or "rules of physics". Similarly, demons cannot just burst through the ground into Erebus and burn up the whole place. They have to be summoned by a portal, an alternate and parallel dimension of existance that cannot be reached via any amount of physical travelling, just like travelling any distance along the surface of the Earth will not get you to the moon.
