Fell & Fidrikon had an idea so interesting it deserves its own thread:
I just thought of something.
Imagine (unless you're a Signer in which case please dont think of anything), an Anti-Sigil on the outside of the Torus... two differant cities in an inverse Bytopia-like situation.
Sigil has portals to everywhere.
Anti-sigil would have no portals whatsoever. And with the Ladys astral lock that means they would have no connection with the multiverse at all.
All that would have to happen for the two to meet is tunnel, hidden deep withing UnderSigil, which joins an Undersigil look alike on the outer side. The reason no ones found it yet: Because Its well hidden and with all the creatures about no one really likes to look around too long.
Could be an intresting Idea. Maybe it could even double as some sort of Sigil shadow plane?
Wouldn't that place the Anti-Sigil really high above the spire, on the Outlands? Then perhaps the place is full of Rilmani? Instead of trusting dabus servants, the Lady of Pain (or her inverse counterpart) rules with the Rilmani as her instruments of balance. Or perhaps the Kamerel (sp?), the reclusive predecessors of the Centered Ones, hold sway in this, their last redoubt? In that case, maybe Unsigil is only accessible through mirrors or the fabled Ordial plane?
Anybody have a good name for the Anti-Sigil? Glyph, perhaps? Logos?
As for the concept of the Anti-Sigil, I've tinkered with an idea similar to this before, only it was about the Spire.
Similar in respect to the conception of "anti-crimes", the Anti-Spire balances all things by elimination but also enhances all things as well as they draw closer to the Anti-Spire itself. Of course, the enhancing factor of the Anti-Spire is directly proportional to the draining effects of the Spire itself... only in the opposite direction -- rimward instead of Spireward. So in effect, it completely balances all things out, but at the same time, cancels out that balance as well.
Thus the paradox that is the Anti-Outlands is born.
The common conception would be to suggest that the Anti-Spire is in fact an "inverted Spire". But that only posits the opposite to the general shape of the Spire, rather than its function... which is the more important element.
I never really defined where exactly the Anti-Spire was, or even if it laid in the center of the Anti-Outlands. The Anti-Spire could have been everywhere and nowhere in the Anti-Outlands... a direct opposite to the physical presence of the Spire. It might also have reached toward infinity just like the Spire above, only downwards relative to a person standing on the underside of the Outlands. For me, the most crucial aspect was suggesting the Anti-Spire as the opposing element of the Spire equation.
As for what the Anti-Sigil in this conception would be like... well...
