Your shouldn't go sideways in fact: Sigil is built so that the buildings on either side have no windows facing "outward".As a Planescape fan, I don't think I'd ever realized a design intent that you could go "sideways" in Sigil and wrap around to the other side of town. And I'd always enjoyed introducing primes to Sigil with the "and the city extends to the horizon and goes up ... up ... up until you can see the other side of it overhead."
A more common nane for the torus is "donut", BTW [emoji6]Sorry Morrus, and more importantly, DMZ2112. Lost my temper there.
@ Aramis Erak: While I'm not up on my geometric shapes, I do understand that a torus and a ring are not the same thing. Your second paragraph makes the distinction clear, to me at least.
But I still fail to see the practical difference between a torus-shaped city and a ring-shaped city when described in "layman's terms". Describing Sigil as a ring, rather than a torus, is technically wrong . . . but who cares? It doesn't make folks who aren't familiar with the term "torus" stupid, or WotC "coddling" or "dumbing down" to use the term "ring" instead.
Before I purchased my first Planescape product, I'd never heard of a torus before. And outside of the Planescape literature, I've never encountered the term anywhere else. If I describe Sigil to my players as a city on the inside of a torus, I'll get blank stares. If I instead describe it as on the inside of a ring, they immediately get it and have a pretty accurate picture (if not completely accurate picture) of what Sigil looks like. Win. I can always later have some smarty-pants Guvner lecture them on the fine differences between a torus and a ring.
Sigil has never actually been a true torus (closed), but is open on the inside of the ring.
I'm not much of a Planescape fan, but I've always assumed that Sigil was on the inside of a torus in the literal sense ie a closed donut shape.As a Planescape fan, I don't think I'd ever realized a design intent that you could go "sideways" in Sigil and wrap around to the other side of town.
I don't really follow this - can you explain with a bit more detail? What do you mean by "sideways"? And what do you mean by "building on either side [either side of what?] have no windows facing 'outward' [what direction is outward, given the whole thing is on the inside of a torus?]"?Your shouldn't go sideways in fact: Sigil is built so that the buildings on either side have no windows facing "outward".

If it's actually the inside of a tyre, than I agree with [MENTION=18182]Dire Bare[/MENTION] - describing it as a ring (especially if the edges of the ring have walls) seems like a very minor difference of little practical significance.Well, it's not properly a torus - but if you imagine the inside of a bicycle tire, with the "sky" where the open part is, you get a city that's got no end in one direction but has walls on the sides.
Here is the original boxed set map - the image at the top makes it clear it's a "tire lying on it's side" rather than a true torus. Which is a shame, I always thought it was a missed opportunity to not make it an actual torus - I never saw the purpose of having an open side.But the picture someone posted upthread looked like a literal torus to me. Or is that picture not canonical?
If I recall correctly, there is actually txt saying the opposite - as Savage Wombat was saying. I recall it mentioning houses up against the edges, with no openings (doors/windows, etc), and that there was "nothing" beyond. Even if you climbed to the top of the buildings and jumped off, you'd jump into nothingness. So no way to fly in or out.There was something in the original books I read for Planescape that implied there was no opening.
