It could be, but I'm not sure how closley tied the Absolute is to the events of Ketheric Thorm and the Dark Justiciars, If the General is Ketheric, then it would follow...This would also play into the, 'Ketheric was driven mad with grief over his dead daughter' theory, because we know that the apothecary was trying to discover resurrection, whatever that means in FR.
I'm wondering if everything to do with the temple is just a side project Ketheric is trying to do on the sly.

Also the first raid was unsuccessful, though it's unclear why, it's also unclear why shortly thereafter, a host from Hell came and destroyed everything in Grymforge.
