I started this a few years ago, not sure where i was going with it and I can't remember what it's about. Any ideas? Perhaps someone could have a go, not in limerick fashion please, at finishing it off?

Lost in Timeunfinished by Jonathan Malory

Once they had cities many but now they have none,
They build their ships and sail the oceans black.
Hearts were pure and swift when once they ruled the world,
Now a hunger fills their souls can’t get their old ways back.

They wander blindly in the night seeking death and fear,
Squandering their life’s essential oils in hope of making good.
