The Issue With Divine Calamities.

Death is not something that they usually worry about because, in the void universe, they are all immortal. If they will resurrect after being killed. The only thing they consider is preparation for a swift resurrection and avoidance of world gods. 

That's why they didn't think anything special of their immortality in this world. It is completely normal for them to come back from the dead.

If there is anything noteworthy about their immortality as gods, it is that resurrection is faster here. But now they know that it is even worse than the immortality that they normally enjoy, as they can lose it and lose access to this world completely.

It also reminded them of their disdain for the gods of the void universe. 

Time passed in the divine realm. Pantheons fought, and gods fell. The gods that fell did so in the normal way. They lost all of their Oracles and had to start again somewhere else in the mortal realm.
