Here's a poem I made using the oaths for all the lantern corps from green lantern...
The darkness grows all light dies.
We crave your heart and your demise;
with blood and rage of crimson red,
ripped from a corpse so freahly dead.
What's mine is mine and mine;
Let those who try to stop what's right
Burn like my power-Sinestro's might!
Let those who worship evil's might
beware my power-green lantern's might!
With strong hearts our souls ignite
look to the stars-for hope burns bright.
From hopeful day to raging night.
Our proud souls soar through the dim twilight.
For those alone in blackest night.
Love conquers all-with violet light.
A new dawn comes.
Let there be light.
