Zodar is a daemon who has found a highly specific sector of psychic real-estate that, while within the demesne of Slaanesh, wasn't receiving stewardship commensurate to its growing presence: smug, self-satisfied amusement. The growing number of prominent individuals who were massively and obnoxiously self-assured has convinced Zodar that he could figuratively skim from Slaanesh and ride the Prince's coattails to godhood.
