Because It is entirely separate from the reality your plot hole is made to devour.Subplot energy is a byproduct of plot energy however, once created it has the capabilities of becoming independent. For lack of better words it creates an existance seprate from reality itself. A sub reality if you will. Since the plot whole only devours matter and energy from the reality that plot energy exists in, it cannot devour subplot energy, for it exists in a completely different reality. and ISE Field is what is created when Subplot energy is harnessed and pulled adjacent to what would be the plot reality, this field can be entered and exited freely by anything with a physical make up, however plot energy and any other form of energy other than sub plot energy cannot pass through the field. Basically our characters are not within the same reality that the plot hole exists in, they are adjacent too it.
First off, if you want people to be able to move through it, you have to let through energy. Kinetic energy is required for movement. Anyone who touched it would be completely unable to move. Their cells would also stop producing warmth and burning oxygen, their blood would stop flowing, and in short, they would nearly instantly die. Which I believe is not the effect you're looking for.
How can it exist outside of reality? If it doesn't exist, then it can't affect anything. If you're saying it can't be affected by the Plot Hole because it's 'outside of this reality' assuming you can explain how that's possible, then that would mean that absolutely nothing could affect it, making it impossible to control or even summon. It must be possible to affect it if you want to use it.
I like the idea of something that absorbs energy. Energy can't absorb energy, BTW. So we could say that you have a SubPlot Field, which, like the Plot Hole, is a complex enchantmen/scientific device, which can be used to absorb Plot Energy. As the Plot Hole uses Plot Energy to grow, it would function as a stabilizer.
