Nobilis/WMG

Lord Entropy is an Excrucian who rebelled against the others.
He has The World-Breaker's Hand, he and his servants seek to destroy almost everything they touch, and he has some special insight into the Excrucians that others lack. His eyes are jet black, but have no stars, because unlike the other Excrucians, he has not consumed any parts of Creation.
 * Sure, but that World-Breaker's Hand costs him 15 character points. 9 for Aspect, 21 for Domain(+14 for two secondary domains), 18 for Realm, 15 for Spirit, 6 for Immortal, 2 for 2 additional DMP's and 15 for World Breaker's Hand comes up to exactly 100 points, which is his listed total character cost. He'd have a discount if he were an Excrucian(I think, not one hundred percent sure on that one). Besides, it's a very appropriate power for an Imperator of Destruction.

Agusta Valentine, the writer of A Philosophy Of Treason, was the Power of Love.
Lord Entropy outlawed Love not for any ideological reason, but simply as a punishment of the Power who had written such a heavily-suppressed book.

Outside The Wall, Unearthly Nobles practice Reverse High Summoning, and call beings from inside of Creation to them.
Superstes Zupay was such a Reverse Summoner, and gained such power that, upon her death, her soul fled inside the Wall, to begin life anew.

The Doctor is the Power of Time.

 * The author of Nobilis actually statted the Doctor up as the Power of Hope.
