Spawned

From the devil, I am spawned
My realm extends from dusk to dawn
Some **** blood, others use fangs
Many find their end, as they hang
What's elixir to me is poison to all
No one can escape the reapers call
Why fight the fight you're doomed to fail
Let go of your beliefs, join me as we sail
In everybody's side, I am the thorn
I am symbolized by the horn
