Who are you?

I always meant to say I’m sorry
for the things I said and did
“I’m sorry.”
I feel better now, do you ?

I am your Antichrist!
I will destroy mankind!
Born of the beast, and the flames, I will devour, I will devide!

While sailing one night upon the deep
Lying in my hammock, I fell asleep.
I dreamed a dream and thought it true
Concerning Franklin and his gallant crew.

In cruel hardships they sailed away
On frozen oceans in the month of May.
To seek a path around the Pole
Where we poor seamen must sometimes go.
