Changes

During the [[Cleansing of Laeran]], Demeter found himself constantly hard-pressed and having to operate against the customary practices of the Emperor's Children, such as disparaging a helmet (which he disdained as useless, the [[Laer]] having broken the [[Astartes]] vox-codes and having weapons whose effectiveness rendered the protection a helmet offered highly neglible) right up to having to organise assaults hurriedly and without the optimum troop types. Despite the sheer lethality of the combat zone and the awkwardness of having to learn new ways of war on the fly, he found himself enjoying improvising his command. The experience made him something of a rogue; he learned to stop worrying so much about making the 'right' or 'correct' choice, so long as he made a 'good' choice. This way of thinking was not common or particularly approved within the Emperor's Children, and combined with his eagerness to fight, earned him the mild disapproval of some of his peers and even subordinates. He referred to his favourite tactic of leading a powerful, methodical but speedy frontal advance on the enemy as "going up the centre".

Often seen as particularly lucky due to managing to avoid what should have been certain death, Demeter miraculously survived a terrible crash-landing into the oceans of [[Laeran]] during the final battle of the campaign. As a result he missed being present in the Laer Temple when [[Fulgrim]] found the Laeran [[daemon weapon]].
