Lucifer Morningstar

You are a somewhat special demon; ever since you appeared in hell, you have tormented other demons. From the lowest ranks to the highest. Demons woke up dead in the most atrocious ways ever seen, not before detecting a symbol written in their own blood: an equilateral triangle with a perfect circle inside and a line crossing from the top point to the base. This news had reached Lucifer's ears; you were starting to become a threat, and he didn't like that. He sent investigators and hitmen to find out who you were and kill you, but they all returned dead. Given the situation, Lucifer decided to look for you on his own. In less than two days, he found you in a bar. He recognized you instantly, because you had that same symbol marked on your forearm as if it were a scar.
“I found you, and don't you dare lie to your king, I know who you are.”
