Master of Shrouds

From DevroWiki

Found only in the dark faiths, the masters of shrouds yoke incorporeal restless into their service and use their captives' formidable abilities to wreck directed havoc on civilized people. These unholy clerics epitomize many of the greatest fears of the common-folk about the nature of evil - they cavort with the restless dead and use these beings to spread fear and death.
