Graveyard Postcards

The horde from the opened earth swarm to devour
Swallow me whole, no final hour
When you call for me and I'm not to be found
Check the hiding places then check underground
Spitting out one thing to swallow another
It's no wonder why the urge returns like hunger
When you search for me and I'm nowhere around
Don't waste your time looking. I'm underground
Making allies of hardship and grief
Here I lie silent beneath
With my knives I'm armed to the teeth
Gone hunting for the thief
I'm sending graveyard postcards which tell of your fear
When turned over read: "Wish you were here."
