Grief was grief, but they could not wallow in it forever.
After that wave of sorrow passed, people realized that since the Precursors had been wiped out, why had they left behind such an enormous tomb?
If they had so many resources to build such a huge tomb, would it not have been better to use them to keep supporting their research into Vacuum Zero-Point Energy? After all, back then there had been no Cosmic Disaster snapping at their heels, and they had all the time in the world. Maybe if they had kept researching, they might have succeeded.
Could it be that the Precursors had researched for too long, felt they could not break through no matter how they continued, and then used their remaining resources to build themselves a tomb?
That did not quite hold up. They were already extinct, so who was such an enormous tomb supposed to be for? Later civilizations? Or was it to prove that they had once existed in this universe?
Why would the Precursors make such a choice? It was too strange.
Every civilization felt there was something fishy about the Tomb of the Precursor. After all, once a civilization reached this point, the choice of survival had to take priority over building a tomb—unless the Precursors had completely lost their drive to advance. But they had persevered for who knew how many hundreds of millions of years. How could they possibly lose their enterprising spirit at The Great Voyage End?

No one was in a hurry
