The Morning Star, Satan, King of Hel (Hell), First amongst the Fallen, the Eternal Sinner.

Created for my rather long BL novel Where Stars End.
I'm not providing a link as it is definitely NSFW ^^;

After waiting patiently for tens of thousands of years, the lonely king of Venus has suddenly decided to mount an assault on Earth. Called Ashravash by the demons of Hel, he is a difficult character to understand even by his closest friends and councilors.

Lucifer seems to have some deep-seated hatred for the angels, but unlike the other Fallen, he still has his feathered wings.

He has earned a reputation for being cruel and blood-thirsty during the war, killing and destroying with nary a thought. Yet, as Cipher has seen during his captivity in Hel, Lucifer has a soft side, and can be almost kind, and as he points out, humans are no less cruel in war, and demons are not into torturing those they do not own. Perhaps his ruthlessness is just a matter of human perspective.

Of the Sins, he is both Pride and Wrath.
