For Persistence...

"For persistence of existence and the future of our kind,
breaking up from all we know of and the doomed ones left behind."
Invincible - moving in from the void.
Insatiable - solarsystems destroyed.

Undisturbed for billions of years seven planets thread their dance in circles,
'round and F-type star, their blazing mother -
by the dark intruder all is squandered!
