High Lords of Terra

The High Lords of Terra are the rulers of the Imperium of Man.

So after Horus got his heresy on, the Emperor had to ascend the Golden Throne to keep him alive. Since he wasn't dead, Roboute Guilliman reasoned that a new leadership was needed to guide the Imperium. He set up the High Lords from the old Council of Terra, with himself as Lord Commander of the Imperium, inviting the heads of the Administratum, the Officio Assassinorum, and the Adeptus Mechanicus to the table as well. While it's plainly evident that they are not making the Imperium better, there is some evidence that they may be making the Imperium worse. So, once again, thanks for nothing, Girlyman.

The High Lords typically include:

• Master of the Administratum: The head of the Imperial bureaucracy, the Master of the Administratum is the considered the most powerful of the High Lords, and they are fucking territorial about that.
• Ecclesiarch: The head of the Adeptus Ministorum, of Ecclesiarchy, the Ecclesiarch briefly usurped the Master of the Administratum as most powerful High Lord. Goge Vandire solved that problem by being head of both, then went nuts with power and had to be killed by the Sisters of Battle.
• Grand Master of Assassins: The head of the Officio Assassinorum, the Grand Master is constantly watched by the other High Lords, out of concern that he might assassinate the others. Mostly because one Grand Master did. Funny story.
• Fabricator-General of Mars: The head of the Adeptus Mechanicus will occasionally take time from meditating on the Machine God to help run the Imperium.
• Inquisitorial Representative: A member of the Inquisition sent to insure that the Emperor's pet psychopaths are up to date on what laws to enforce.
• Parternoval Envoy: Representing the Navigators, this guy makes sure that the Navigators have a say on what's going on, so they won't get declared abominations to the holy human form.
