Destroying a Demiplane
« on: April 01, 2012, 04:46:00 PM »
I am looking for a way that would allow the destruction of a Demiplane made by a Genesis Spell.
I was certain I have seen some spell floating around that could do this, but I can not remember the source if it actually exists. Any other method is acceptable as well.
Please and Thank You.
Im really bad at what I do.

Fimbulwinter with CL tricks, maybe. That could turn it pretty much uninhabitable.

Wish to un-genesis?

You could probably just do enough damage to destroy the entire thing.  Reserves of Strength will come in handy for that.

The real question is, how do you destroy an infinite plane?  My thought there is that you'd have to set up some kind of chain reaction... think the Little Doctor.  But that would take an infinitely long time to destroy an infinite plane unless you can get it to diverge super fast...  thoughts?

An item of antigenesis and wish x2(for 2 identical items to continue the chain reaction)?
If you set the trigger right it oughta expand infinitely fast.

If one assumes that damage is enough to destroy a plane, infinite damage could destroy an infinite plane.

Not quite... you need infinite damage at infinite range.  A demiplane has a fixed size.

Antigenesis?
The psionic version of genesis has a destructive use:
Quote
Antigenesis

If genesis is manifested on the Material Plane, the power takes effect and the demiplane begins to grow at the rate noted above, but it gets no larger than a radius of 1 foot per level. The energies of the new plane are exactly canceled by the energies of the original plane, creating a dead spot like a limited cancer on the original plane. The expanding boundary of the dead spot wipes away all construction, crumbles natural land forms, and evaporates water, leaving behind a uniformly level area of inert dust. Living creatures that pass the boundary of the growing dead spot are not directly affected, but plants can find no sustenance in the dust of the dead spot, water-breathing creatures die quickly when water turns to dust, and mobile animals know enough to leave the area alone. Once the wave of change passes, no special essence remains in the dead spot, and it may be colonized naturally over the course of several years by bacteria, plants, and animals.

That relates to a question I asked some time ago, which wasn't answered. If the plane has fixed size, what happens if you try to dig through the "floor"?

In physics, if you reach the end of a reality, mo energy can exist in the lack of reality. Therefore, you couldn't dig through the floor, as the shovel or whatever could not maintain the momentum.
In other words, you can not pierce what does not exist.

And on that note, damage could destroy everything on / in the plane, but would not destroy the plane.

Or a  1st level power Linked psi Anti-Genesis item.
Triggered every round, it'll "deaden" a rather large area.

But even 1 Genesis cast early enough will be geometric,
opposed by a massive amount of Anti-Genesis-es
comparatively linear ... the maths should allow that
original Genesis to keep expanding.


What works against Instantaneous effects?

Anti-Genesis only triggers on the material plane.
Anti-Genesis still has the 1,000xp cost
Anti-Genesis only affects 1ft per caster level radius maximum, and requires a growth period of 1 day per foot.
For the item: Triggered every round, it'll overlap. No further effect. No stacked expansion. You'd need to move the item around. You'd get killed my every Druid in the world. Even Blighters, as they'd want it for themselves.

Conclusion: Anti-Genesis sucks. Unabatedly.

I assumed that the wish part of the item could create them a set distance away from the original.
Otherwise, agreed.
Using some other spell than antigenesis, you could probably destroy everything on a plane, but the plane would still exist.

You could try a warblade who is affected by the plane's existence, maybe.

I guess Iron Heart Focus could work in regards to what I am trying to accomplish.

My main intent is to create a means of Interstellar Travel  through the use of multiple Demiplanes crossing through a point on the Prime Material and a central point on another plane.
With this we could create a Intergalactic Highway for our use. The only problem with this is opening Demiplanes to hostile regions of the Prime Material and not being able to close access through the Demiplane. Of course we can make use of Portal Keys and the like, but I would rather be able to permanently destroy the Demiplanes if possible, or alternatively remove portals to the Demiplanes.

Uarcumn, The Mageocracy in the campaign world, is currently being invaded by (Presumed)Count Strahd's Undead Army (which are characters from a different game accidentally let free when Expedition to Castle Ravenloft went awry, because my group really just does not like Ravenloft, mainly because everything wants to eat you) and they are using THEIR portals as a means to invade the country, and when the current objectives are done, they are the ones most likely to support us. Preventing the possibility of being invaded through out own portals is definitely going to help win their support.
Im really bad at what I do.

More accurately, it depends on the geometry of the demiplane's space. If it's closed in all dimensions, then you'd loop back to another edge of the demiplane (more accurately, the entire thing would be a closed infinite loop in all directions, but completely continuous; the concept of the edge would only make sense if modeled in 4 dimensional space). I'm not really qualified to claim what would happen if it's open, but intuitively it feels like a non-infinite demiplane must be closed. At any rate, there's no sensible concept of "end of a reality" in physics, as far as I know. I feel like you're making up that thing you said.

hmm ... tangent ...

What if in the middle of the Prime Material plane,
you had a small piece of the Plane Of Dust,
(brought in by say the PrC in Manual Of The Planes)
and you cast/-fest Anti-Genesis on it.
The Dust-Plane part turns to "dust" but it is not
the exact same kind of dust.  It's kinda like an Anti-Plane.
Same thing with Earth or Negative Energy.
The opposite of Earth is Air, but this turns into dust.
Negative gets turned into the dust, even though Earth had nothing to do with it.
Dust-Plane is Earth plus Negative.
Earth gets turned into the dust.
Dust gets turned into the dust.
Negative gets turned into the dust.

Soo ... Anti-Plane ...  :???
This seems to be a new type of substance.
