Given than the Millenarian math of Saunt Edhar stores a large amount of nuclear waste, one would expect all Millenarians to have died out long ago from radiation poisoning or radiation-induced cancer, but they haven't. Anathem explains this away as a case of quantum immortality: there are narratives in Hemn Space where Millenarians miraculously do not get radiation poisoning or cancer despite essentially sitting on top of a nuclear dumpster, and as Incanters they can simply access these particular narratives.
But then, if the radiation leakage is so severe, it should also affect the Centenarian math next door. But so far as we know, Centenarians do not die of cancer. So, we have various possibilities.
- Centenarians are also Incanters, and can survive adverse radiation effects in the same way as Millenarians. This would be consistent with the fact that Logodhir, while only a Centenarian, is a Rhetor, which is an ability implied to be on a par with Incantation.
- Centenarians are not Incanters. Millenarians choose the cancer-avoiding narratives not only for themselves, but for everybody in the concent and surrounding area that could potentially be affected by radiation. This is consistent with the fact that Millenarians are able to drag others along into the narratives they favor (as Jad did with Erasmas).
- Nobody has to avoid radiation poisoning because the waste containers are perfectly secure and leak no radiation at all. Millenarians using Incantations to reach prodigious ages is something they do because they can, not a side effect of having to use Incantations to avoid dying of cancer.
Which one do you think is the most likely possibility?
