When the Lady's edict hit the small remains on the Doomguard left in Sigil, they really stopped caring.  The Armory was destroyed, their spheres of anniahlation gone, and they were betrayed by their leaders time and again, leading to the near destruction of the faction, seeing fullfilling their beliefs.  However, four negative-quasielemental citadels hold out hope, but are cut off.  Those loyal member, alnog with the loyal from Sigil and those planewalking still exist however.  This is what they have become.
      Hit Dice: d10

Requirements:
        * Base Attack Bonus: +6
        * Disable Device Skill: 5 Ranks
        * Knowledge (Architecture & Engineering): 3 Ranks
        * Feats: Cleave and Sunder

Class Skills:
        The class skills of the Sinker (with key attribute) are: Bluff (Cha), Disable Device (Int), Disguise (Cha), Forgery (Int), Innuendo (Wis), Intimidate (Cha), Knowledge [Architecture & Engineering] (Int), Read Lips (Int), and Sense Motive (Wis).  Sinkers get 2 + Int Modifier per level.
 

Class Features:
        All the following of the Sinker prestige class:

      Weapon and Armor Proficiency:  Characters who take a level of Sinker become proficient in all simple and martial weapons, all aromors, and all shields.
      Entropic Blow:  A Sinker can channel the destructive energy of entropy into extra damage they cause in a melee attack.  Declairing the Etropic Blow before attacking, if successful, she causes her Sinker class level times two plus her charisma modifier as additional damage.  This works on all living matter, but is even more effective against non-living matter.  When used against an object, constructs, or even undead, the entropic blow causes double total damage and ignores the objects hardness.  If this supernatural attack misses, the Entropic Blow is wasted.
      Doomlord Title Available:  Only characters who have at least one level of Sinker may become either lesser or greater Doomlords.  See the Factol's Manifesto for more information reguarding these character options.
      Sifting: Being so knowledgable about the ways of destruction and decay, 2nd level Sinkers can sift through the destroyed remains of an object or a living being and gain knowledge.  After a minute of study, the sinker will know:
                Object - What it was, what it looked like, how it was destroyed, how long it has been destroyed, and who or what destroyed it.
                Living Being - What it was, a physical description of being (enough that a familiar being is recognized), it's age at time of death, how long it has been dead, how it was killed, and a vision of it's last minute of life.
        This supernatural ability is usable at will, but requires physically going through the remains.
      Destructive Expertise:  As the agents of destructive power, Sinkers of at least 4th level gain +10 insight bonus to skills checks for Disable Device or Knowledge (Architecture and Engineering).
      Doom:  This allows the Sinker to cast Doom as a sorcerer of the Sinker's class level once per day.
      Erase:  This allows the Sinker to cast Erase as a sorcerer of the Sinker's class level once per day.
      Shatter:  This allows the Sinker to cast Shatter as a sorcerer of the Sinker's class level once per day.
      Death Knell:  This allows the Sinker to cast Death Knell as a sorcerer of the Sinker's class level once per day.
      Disintegrate:  A 10th level Sinker may cast Disintegrate as a sorcererof the Sinker's class level once per day.  This ability is a full round action.
