Prince of Darkness (Lords of Shadow)

The Prince of Darkness is the title of a ruler of the forces of evil on Earth and in the netherworld in the Lords of Shadow universe. He is an evil counterbalance and enemy to God, with power surpassing that of the Lords of Shadow and second only to God's. He may also be the Lord of the Castle to a demon castle, and the ruler of a demon castle is not necessarily a Prince of Darkness (for example, Carmilla). Interestingly, there can be more than one Prince of Darkness, as seen with the rise of Dracula, Satan being the first.

As the personifications of evil, each Prince of Darkness rules a demonic dominion (Hell for Satan and Castlevania for Dracula). However, motivations can be startlingly different: Satan wishes to rule Earth and Heaven as the new God. Originally, Dracula wanted to avenge himself on the Brotherhood of Light and remake the world in his image; but as time passed, the vampire lord came to view himself as a necessary monster so that worse monsters like Satan and Zobek would be unable to take his place.
