Devourer Of Worlds

I have travelled across spaces,
created by me milleniums of time before.
When I returned to them all before was created,
had changed.
Light's worlds were only darkness now.
All the effort was in vain,
the same creatures that I create,
devoured their own way of life.
They implore in temples wich I unknow their sape an origin,
to rescue me.
My only reason to be is to put and end to them,
who are destroying ourselves.
Because I am the Devourer of Worlds.
