God of Construction naturally didn't have any back-up plans in place.
Some of the powerful deities had some premonitions, but it was already too late for them to stop it. Those who had a good relationship with these powerful deities were given some hints and made preparations in advance. Only the God of Construction remained clueless until the end, and no deities helped him.
If the Heavenly Palace was a class, then the God of Construction would be the invisible one that every class has. No one liked him, and no one hated him. It didn't matter if he was there or not; nobody noticed.
However, in the Lower Realms for tens of thousands of years, there were people like carpenters and tile workers who would always worship their Ancestral Master and, in passing, mention the names of related deities, including the God of Construction.
