I think The Meek has many great equivalences that could add to a big, coherent post-apocaliptic story:
Happens in California, allowing for parallel events without contradiction,
happens well in the future (around year 700, supposing simmilar time of beggining for counts),
has humans as protagonists, with isolated magic capabilities,
has shown evidence of old world infraestructure,
etc.
Overall, both are really well made stories, aside from amazing images
