Description: An Ætheric Dominion represents one of the innumerable hosts of daemonkind, each of which is sworn to a greater entity that resides within the Warp. Those encompassed by the same dominion share similar features and behaviours, embodying a primordial force or idea given physical form. Most will share identifying features that link them with the inscrutable patron they serve, providing the smallest sense of unity across a daemonic host.
Any unit with the Ætheric Dominion (X) special rule will have a number of additional special rules and abilities specific to their Ætheric Dominion. A unit which includes models with this special rule may only have one variation of the Ætheric Dominion special rule, e.g., Ætheric Dominion (Encroaching Ruin), and no model with this special rule may join a unit which includes any models with a different variation of the Ætheric Dominion (X) special rule.
A unit which includes models with this special rule without a specific Ætheric Dominion listed in brackets must select one Ætheric Dominion from the list that follows during the army selection process (before the start of a battle) for no additional cost and is thereafter treated as having that variation of this special rule. All units within a Detachment must have the same Ætheric Dominion (X) special rule. A Lords of War choice taken from the Ruinstorm Daemon Army List may select any Ætheric Dominion (X) special rule, even if it is different from the one selected by the Primary Detachment.
