Dread Host
Fear is a familiar weapon to the Imperium, used to deter enemies and keep seething populations in line. There is no terror as pure and absolute as that invoked when the Emperor’s own fury is unleashed to punish his foes. Such is the Dread Host, a weapon forged to strike at dawning threats and spread fear through absolute annihilation.

SHIELD HOST FIGHTING STYLE: INSTRUMENTS OF THE EMPEROR’S WRATH
The Dread Host are executioners and eliminators the Emperor’s wrath made manifest. Where they tread, the enemy are completely destroyed. No other result is acceptable.

Trait 1 (changed make dread host beefier when charging instead of harder armor piercing)
Each time a unit with this trait declares a charge, increase the toughness of models in that unit by 1 until your next turn.

Trait 2
You can re-roll charge rolls made for units with this trait.

Martial Ka’tah: Dacatarai

GOLDEN LIGHT OF THE MOIRAIDES 2CP (cleans up wording that all deepstriking dread host units this turn benefit from this stratagem and adds +1 to charge for improved chance of succeeding that charge from deepstrike)
Dread Host – Strategic Ploy Stratagem
The Dread Host go to battle aboard the trio of terrifying pre-heresy warships known as the Moiraides. These potent vessels teleport their passengers straight into battle, so that the Adeptus Custodes can begin their charge aboard a warship, and complete it surging from an explosion of golden light into the enemy's midst.
Use this Stratagem in your Command phase. Until the start of your next turn, when a DREAD HOST unit from your army is set up on the battlefield using the From Golden Light ability:

Each time an attack is made against that unit, subtract 1 from that attack’s hit roll.

Each time that unit declares a charge, enemy units cannot fire Overwatch or Set to Defend against that charge.

Each time that unit makes a charge roll, add 1 to that charge roll.

WARLORD TRAIT: ALL-SEEING ANNIHILATOR (no changes)
The Dread Host employ a near-prescient intelligence network to foresee their enemies’ plans and weaknesses. This warlord employs that amassed knowledge to best direct his comrades’ attacks.
In your Command phase, select this WARLORD or one friendly DREAD HOST CORE unit within 6" of this WARLORD. Until the start of your next Command phase, each time a model in that unit makes an attack, an unmodified hit roll of 6 scores 1 additional hit.

RELIC: ADMONIMORTIS (perfect the way it is)
This towering castellan axe was wrought to make a bloody example of those who dare to set themselves against the might of Terra.
DREAD HOST model equipped with a castellan axe only. This Relic replaces a castellan axe and has the following profile:
WEAPON RANGE TYPE S AP D
Admonimortis (shooting) 20" Rapid Fire 1 5 -1 3
Admonimortis (melee) +3 -3 3

Aquilan Shield
Certain servants of the Emperor bear great responsibilities deemed directly relevant to the safety of Terra. Such esteemed figures are afforded the protection of the Aquilan Shield, until their usefulness is thought to be at its end. These warriors devote every iota of their strength and will to the defence of their assigned charge, be that an Indomitus Crusade Fleetmaster or a lowly Imperial Guardsman turned visionary prophet.
SHIELD HOST FIGHTING STYLE: SHIELD OF HONOUR
Knowledge as to the purpose of the Aquilan Shield’s warriors is rare to any but themselves, and only they know what terrible events will occur if they fail. Thus, they fight with a tenacity and determination that is all but impossible for the foe to overcome.

Trait 1
CORE units with this trait are eligible to perform Heroic Interventions as if they were CHARACTERS.

Trait 2 (They used to just get armor of contempt. boring. This ability might be too powerful but it is on theme)
Each time an AQUILAN SHIELD INFANTRY or AQUILAN SHIELD DREADNOUGHT unit with this trait is within 3“ of a friendly IMPERIUM INFANTRY CHARACTER unit that is allocated an attack and fails the saving throw, but before any ability that would negate damage is resolved, the damage for that attack can instead be allocated to that that AQUILAN SHIELD INFANTRY or AQUILAN SHIELD DREADNOUGHT unit.

Martial Ka’tah: Salvus

GILDED GUARDIANS 1CP or 2P
Aquilan Shield – Strategic Ploy Stratagem (since Salvus is their favored Ka'tah I thought they should have something to do with shooting. This seems fair especially with the alternate cost and the need for the charge to be declared against the character)
It is second nature for the warriors of the Aquilan Shield to place themselves between their charges and potential peril.
Use this Stratagem after an enemy unit has declared a charge against an IMPERIUM INFANTRY CHARACTER unit from your army and before the charge roll is made. Select an AQUILAN SHIELD INFANTRY or AQUILAN SHIELD DREADNOUGHT unit within 6” of that IMPERIUM INFANTRY CHARACTER unit, that AQUILAN SHIELD INFANTRY or AQUILAN SHIELD DREADNOUGHT unit can shoot as if it were your Shooting phase, but it can only target that enemy unit. If you selected an AQUILAN SHIELD INFANTRY unit that contains 3 or fewer models, this Stratagem costs 1CP; otherwise, it costs 2CP.

WARLORD TRAIT: REVERED COMPANION (this unchanged warlord trait and the unchanged relic below paired with Trait 2 gives an opportunity to use a Guardian Shield Captain who is going to be another character's best friend)
Years of interposing himself between his charges and the blades of their foes has left this warlord adept at turning and deflecting attacks.
Each time an attack is allocated to this WARLORD, halve the Damage characteristic of that attack (rounding up).

RELIC: PRAESIDIUS (same as it ever was)
Fashioned by the great Terran armourer Annah Tsvochakin in the latter years of M32, the stunningly worked storm shield named Praesidius is a singular artefact. Not only is its auramite surface finely worked and layered at a molecular level for greater durability, but nestled within its graven bulk are a series of microshield generators. Employing a never again replicated modification of displacer technology, the shield generates small localised displacement bubbles at the point of impact, literally beaming bolts, bullets and the tips of blades harmlessly away from Praesidius’ bearer.
AQUILAN SHIELD model equipped with a praesidium shield only. Each time an attack is made against the bearer, subtract 1 from that attack’s wound roll.
