Doomed to the fierce flames, -- Gwyn has fire breathing
Disproving and close to death -- Close to death, recent thread with Mauja who is severely injured, son of Archi who has killed before
Flames turn halcyon and sterling -- Halcyon = bird creature thing. Dragons are close to that.
Their wrath is only a mirror of your own -- Gwyn's feelings reflect Abraham's
The heart as contrite as ashes,
Safeguard my end. -- "Guarded" Mauja.
Holy water cannot help you now
Thousand armies couldn't keep me out
I don't want your money
I don't want your crown
See I've come to burn your kingdom down
