The "Empty Vessel" Ascetics have shown progress. They can be kept in a "dormant" stage, which allows them to move about, interact, and even take part in priestly rituals with minimal danger (as long as they are closely monitored and not accidentally activated).

I recommend manufacturing MORE than is deemed necessary. If not used, then they will naturally deteriorate over time.

But as they say, "many hands make light work".

And we have truly heavy burdens to bear.
