英语翻译铠甲幽黑的骑士自天降临,雷霆万钧.黑色的圣枪将世界一分为二,一半是海水,一半是火焰.-----------------------------------------就这几句,想要营造一种庄严的气氛（笑）,所以请用正式语XD

The knight in dark armour falls from the sky,
as the lightening strikes and the thunder growls.
A black spear tears apart the world.
One comes the ocean, and the other flame.
应该可以写得更好，有那种古典魔幻文学的味道才对。所以韵律很重要。

The knight with solemn black armor descends from the sky
Accompanied with devastating thunderbolt
The world is separated into two by the dark holy spear
One part is the ocean, the other called the blazes
(the blazes有火焰和地狱的意思，一词两用～)

The dark sacred spear cuts the world into two,
one of which is sea water,the other is blaze.
