Necrons, a dying race or not?
Slight spoilers for Devourer below:
At a point somewhere near the latter stages of the book, it is revealed that there exists necrons who are not true necrons at all. Instead, these individuals are referred to as "false necrons."
Now, the case could be made that all necrons are of the same nature. The major difference between necrons and false necrons is that false necrons were not alive at the time of biotransference. Instead their minds are artificial intelligences based on the minds of former generals and nobles of the necrontyr. True necrons are the minds of those who were alive for the pact between the c'tan.
However, it seems apparent for their brief time in the book that these false necrons are capable of rational thought, military action and better than their counterparts, loyalty. Further, in a tomb world that was wracked by the flayer virus, the false necrons remained seemingly unaffected to a man... cron.
Added to this the fact that many true necrons have a somewhat loose grip on their sanity, I wonder if the slow "deaths" of the true necrons (who, it is confirmed are well capable of dying permanently now) would actually diminish the tombworlds, or slowly make them more efficient?
