In its true form, an utukku looks like a 7-foot-tall, 200-pound-heavy scaled humanoid with a single eye where a face should be, surrounded by wriggling tendrils. Its arms are sucker-tipped tentacles.
An utukku teaches its followers that they will be rewarded not via transformation into an outsider, but by assimilation into the Great Beyond itself. After death and Pharasma's judgement, the souls of an utukku's cultists are converted into quintessence that then merges with and bolsters the Abyss instead of becoming petitioners, denying the demons a soul that they can use to create more of their kind.
