The Sinister Six
Roscoe Jenkins is the undead ghost of a powerful wizard haunting Kael Varda. The ghost previously inhabited the form of a copy of Kael created by a shadow assassin spell, known to the party as The Mysterious Man, but Vanessa Mackelroy‘s dispel magic revealed the ghost’s true form.
Over several encounters, the party learned that Roscoe was a powerful eidoloncer capable of casting devastating spells, in addition to his terrifying ghostly powers – only the ghost’s restrained enmity kept the party from being obliterated. Eventually, the group was able to strike a deal with the ghost for a cessation of hostilities in return for the resurrection of Roscoe’s innocent grandson, Caladorn Jenkins.
The enraged ghost appears to have disappeared since the resurrection of Caladorn, the mage’s grandson, but only time will tell if he is gone for good.
