Re: Le Grand K's fate
It will be put in a museum with great fanfare, then as interest in it wanes, will be moved by degrees to less auspicious locations, until it is almost forgotten. There will be a brief resurgence of interest when it is stolen to order for some obscenely rich person's private collection.
In tens of thousands of years time, archeologists in special protective gear will find it while searching though the highly radioactive remains of what appears to have been a fairly advanced civilisation. Recognising that it contains important metals that are in short supply it will be immediately taken to the Whole Earth Technology centre to be put to use.
