I agree with the points raised by Lephyr and Epyriel, but there are also a few things I would like to bring up as well
While I'm quoting this one sentence, I more so wish to address the idea of Sidious scaling to his Force Storms in general, regardless of if they're 1-C or not (I don't think they are)
As stated (by Palpatine himself) in
the Book of Anger, Force Storms are born from the "hidden reservoirs of Dark Side Power" and "the energies of the Dark Side of the Force". These are clarified as referring to "the Dark Side Power that
permeates the Galaxy" and "the Dark Side energies
that are all around us". Combine this with the
Jedi Path referring to Force Storms as a "demonstration of
pure natural energy", and it would appear that Force Storms are not entirely fuelled by Sidious' own power, but also require the use of external sources to create.
I'm not stating that Sidious' own power doesn't contribute to the creation of the storms, but it seems as tho their creation also requires pulling from the natural energies of the universe, which if this is the case then Sidious wouldn't scale to their full output.
This isn't entirely true. While Sidious can control these storms to a degree, he cannot control them fully
as confirmed by the endnotes written by the author, which state "... and he now boasts to Luke that he has perfect control of his Force Storms!
Whether such boasts are true or not (they are not),..."
What your quote actually says is
I wouldn't exactly say that the text emphasises "Hyperspace" in any significant way compared to anything else in the text. If anything, it is highlighting the exact opposite of what you claim. The first half of the sentence is listing the objects in realspace that the storms can transport, and so the simplest interpretation of this is that the storms are consuming every OBJECT in its path (i.e. the stuff it spent half the sentence focusing on), not that it can consume the means of transportation (which is only given 2 words, so clearly not the emphasis of the sentence).
Not a single quote/scan you have provided EVER refers to the storms effecting "the fabric of ALL space and time". The only one that even remotely does is the
comics companion quote, and even this just references "all of space" which likely just refers to real space.
No, fan wikis are not accepted as valid evidence as they simply offer their own interpretation of the material. The wiki being linked to on the profiles is not an example of them being valid, but is more so an example of the profiles being massively outdated / poorly made.
