Clocks.

The clock strikes one,
"Sire, can we have some fun?"

"Burn the houses, slay the mortals.
Destory the castle, Open the demonic portal.
For when thy work is done,
Thy shall have some fun."

So the houses were burnt and some mortals were slain,
The castle was grounded, and demons let loose pain,
Flames engulphed thousands, and men gasped for air,
They called for their god, but no one was there.

When the ruckus had settled, the winds grew calm,
and the debris was starting to cool, you could smell the napalm.
A shadow slouched over a pile of the rubble,
The very same shadow, that brought forth all this trouble.
