Lich, Draugr, Poltergeist, and Phobetor: a neutron star system

Unless people are Just  Plain Wrong about what the island of stability means, it would seem to me that anyone experiencing time at the same rate we do would find them too ephemeral to be valuable.

Not microseconds. Potentially up to tens(hundreds?) of million years.

There's also the point that with current technology, it's really hard to make the most stable isotopes of the heaviest transuranics. The reason is that the heavier the nucleus is, the higher the optimum proportion of neutrons is. Given that we currently make the really heavy stuff by bombarding heavy actinides with fairly big nuclei, we still come up quite a few neutrons short. As an example, one of the syntheses recently was done with calcium ions, using californium as a target.
