Here There Be Dragons

I have known those who lock up their love
In ventricular vaults, watch it glisten and gleam
Against blood-covered walls in their four chambered hearts.
They become dragons,
Clutching their gems in shivering claws
While lusting after love,
Still more love,
More jewels to fester blindly
In the darkness.

I originally intended for this poem to be about why it's worth it to invest in people even though there's a risk factor. If you don't, all the love you have isn't worth a thing in the world. Now I think it can mean several things, though, so feel free to form your own opinion!
