Failed avenues of investigation Options

[Netheril]

To save duplication of effort, this is a list of things that we have looked into and will simply not work, according to my divinations anyway. Whilst I am not a skilled diviner, my mother hates deception and trickery, so it is all but impossible to deceive me. I got answers to these questions, so they will be the truth:

Healing the flaw inside me or Sinsanium. The ritual just reverts to target the throne of glass as a default.
Me or Sinsanium is dead or not in existence when the ritual strikes. Again it defaults to the throne.
A series of stacked counter-rites, sufficient to protect the Throne. These were common fare a few years ago.
Making a ritual simulacrum of you that, for all purposes supernaturally is you, and then with your consent vanishing you when the rite hits Target as many of the rites on you as possible.
Creating a series of disruptions in the 'nacht to disperse the power so that it has insufficient strength on Primus to create the desired effect
Increase the strength of the boundaries around the planes where the rites are held, such that the power conveyed cannot effectively leave them
Use focused assaults on Primus targeting the rites on the other planes to disrupt the flows of energy at the time they should be activating - as above so below.
Place fragments of Nagrech on each of the planes in question such that the rite targets them instead.

Combined with other research others are doing the first of these has become a potential option but it is a very slim chance currently. Very slim indeed. It may be a waste of time but there is some small potential growing.
