His save is invulnerable.
Abilities:
Aetaos'Rau'Keres counts as an Icon of Chaos.
Enemies taking Ld tests as a result of losing a combat involving Aetaos'Rau'Keres do so at -2.
Psychic powers and Demonic Gifts "hitting" Aetaos'Rau'Keres may be reflected back at the user on a D6 roll of 4+. Thereafter, shooting powers hit automatically (i.e. no to hit roll, just reflection roll); any powers which involve both the user and the target (e.g. Mind War?) count Aetaos'Rau'Keres as the user.
Ranged attack: 48" range, Assault 1, Large Blast. When the position of the template is determined, a new unit composed of 1D6 Horrors is placed on the template. Thereafter they behave exactly like a unit of Horrors from C:CD that had arrived that turn, although they cannot shoot on the turn they arrive. Furthermore, they do not give Kill Points or Victory Points to the opponent.
Last ranged ability: If Aetaos'Rau'Keres stands still, he may call down an Apocalyptic Barrage (D6) anywhere on the table. This wounds on a 4+ at AP3. However, before the template is placed he must take a Ld test; if he fails this the opponent may make the attack. Furthermore he may not fight in assault in the turn this ability is used.

I'm not sure if it's true, but interesting none the less. There are some suspect issues with them...
