The shrine’s black aura is the catalyst of the foul mystic transformations. The shamans use defiled waters and all the foulness they can scrape up (literally) to create a paste that leaves a permanent residue (often seen on the hands of trap masters and priests) most commonly referred to as Wormtaint.
A Wormtaint Warren is commonly made in a deep and covered warren within the settlement. There are fumes that stay down in the deep pit, safe for those workers that have the taint to breathe, but even the Orrish will writhe in agony as the fumes scar the lungs and cause respiratory bleeding.
This empowers various living creatures to give birth to horrid off-spawn and transforms equipment and when ingested creates a rapturous resolve in the ingester if they are Orrish, Wormtaint is not for the common Orrish. Its effects are concentrated in the hands of the elite – shamans, priests, trap masters, darklings, and champions. The permanent residue upon the hands of a Orrish priest of the Church of Darkness allows them to handle and work with many items and materials of foulness that normally would kill those in such close proximity to the raw work.
