Скажем так, после открытия Великого Разлома от этой сущности (она ведь заперта под горой Анарх...?) весь Титан аж трясло.
Blackest Night
From the Augurium on Titan comes the combined screams of Prognosticars as the psychic signal of the Cicatrix Maledictum reaches them, mere days before the first warp tears affect realspace. With the Astronomicon extinguished, it is realised that prophetic visions more than six thousand years old are coming to fruition.
This grim knowledge is made all the worse by the fact that, as the Great Rift begins to tear open, a rumbling grows stronger and stronger on Titan until the entire moon is beset by ceaseless, ground-splitting quakes. The epicentre of these quakes is deep beneath Mount Anarch, directly below the Chambers of Purity.
