Moderatus

A moderatus (pl. moderati) is an officer of the Adeptus Mechanicus' Collegia Titanica who serves as a member of the crew of a Titan under the leadership of that god-engine's commanding princeps. Moderati are specialist crew, the exact number of who are present and the roles they play dependent on the class of the Titan they serve on as well as the doctrines of their parent Titan Legion.

Each moderatus is given responsibility for operating and monitoring a different Titan system, such as the sensors, the helm or a specific weapon. The moderati add their own oversight to the commands of their Titan's princeps that are fed through the god-engine's Mind Impulse Unit, a device that cybernetically links together the minds of the princeps and the moderati with the Machine Spirit (artificial intelligence) of their Titan.

Several moderati are usually stationed at the princeps' side within the "head" of the god-engine, while others are located elsewhere in the Titan's mighty form -- the gun moderati, for example, are often stationed in the carapace as near to their weapons as the Titan's complex anatomy allows.

As a result of the battles they come through together and because of their link to their Titan's Mind Impulse Unit, princeps and their moderati are often more closely knit than most families. Being linked to the MIU can also be dangerous and even lethal, as the potent Machine Spirit of a Titan can wreck an unprepared individual's consciousness and drive them to madness.

Damage to the MIU system's circuitry can cause the MIU to go haywire, and in such circumstances, the luckiest members of the crew are killed instantly by the psychic shock, while the rest are reduced to gibbering lunatics.

Most of the crew members' connections to the MIU are equipped with manual emergency cut-offs; however, sometimes the moderati and princeps are not able to utilise them quickly enough to avoid the damage. MIU links are attached via implanted cybernetic socket connectors in the cranium and neck, or in the body armour the crew wear. The armour's role is to shield them from secondary damage caused by shrapnel and impacts, and it additionally contains power and life support units, also attached by umbilicals to external devices.

These umbilicals have many redundant channels, so that if any one is severed in the heat of battle, another can easily take its place, making sure that nothing impedes the crew's ability to fight.

Roles[]

The "moderati majorus" are moderati who are given oversight over a Titan's major weapon systems.

The "moderati minoris" are those moderati who are given command over a Titan's minor weapon or other support systems.

Ranks[]

Moderati only have two ranks, which are granted based on their seniority within a Titan's crew and the importance of the Titan systems which they oversee. Senior moderati are given the title of "moderatus primus" and more junior moderati are addressed as "moderatus secundus."

Notable Moderati[]

• Jonah Aruken - Jonah Aruken was a moderatus primus of the Legio Mortis Imperator-class Titan Dies Irae during the Great Crusade and Horus Heresy. Aruken's ambition, as was true for most moderati, was to eventually become the princeps of his own Titan, a dream he felt would be jeopardised if the Dies Irae' commanding Princeps Turnet believed he was involved with the forbidden underground cult of Emperor-worship known as the Lectitio Divinitatus, like his friend and fellow moderati Titus Cassar. During the Battle of Isstvan III, as Cassar prepared to kill Turnet to stop the Dies Irae' betrayal of the Loyalist Space Marines on Isstvan III, Aruken's ambition led him to kill his friend, which allowed the Dies Irae to carry out the mission assigned to it by the Warmaster Horus and turn on the Loyalist Death Guard Astartes it was supporting in the battle for the Choral City.
• Titus Cassar - Titus Cassar was a moderatus primus of the Legio Mortis Imperator-class Titan Dies Irae during the Great Crusade and Horus Heresy. Cassar was secretly a member of the underground cult of Emperor-worship known as the Lectitio Divinitatus in direct violation of the Imperial Truth. Cassar was often ridiculed for this belief by his friend and fellow moderatus Jonah Aruken, though the two rescued the Remembrancer and future Imperial saint Euphrati Keeler from the mute assassin Maggard sent to slay her by the Warmaster Horus. During the Battle of Isstvan III, after the world had been ravaged by the firestorm unleashed by the aftereffects of the virus bombing ordered by Horus, the Dies Irae' Princeps Turnet ordered his moderati to open fire on the Loyalist Death Guard Astartes they had been providing fire support to. Cassar confronted Turnet with his autopistol to stop that betrayal of the Emperor. However, Aruken, fearful that such a betrayal would end his chances for promotion within the Legio Mortis so that he might one day become a princeps himself and command his own Titan, killed his friend instead. The Dies Irae then completed its assigned mission and sought to kill any Loyalist Astartes who had survived the viral bombardment.
