William Black

William Black is the father of Reginald Black and a fellow priest of Sirius. He told him tales of Rygax's adventures in the Shadowfel, but disappeared suddenly when Black Jr was still a child.
He has recently been rediscovered as one of Swayne's prisoners within Mount Pillar. He had been kept imprisoned there for many years (possibly ever since his abduction), constantly forced to watch disturbing visions of the local Grisgol's tragic life, which rendered him catatonic. However, he recovered to an extent when he saw his son, although it took a little while for him to believe that he wasn't an illusion.
After Rygax saved The Party from Swayne, he sent William back to the Fadelands along with Zaheer and Daggerface, as they had not been affected by the Curse of Netharin and so were not plane-locked. They made it back to the base of Grandmount, where they met up with Westshire Wes's group and stayed in their camp until The Party returned for them, during which time he regrew his face.
He then travelled back with them to The Basilica, where he remained until the epilogue, in which he joined his son on a diplomatic mission from The Hand to Marcus Jonasson.
He seems to be on friendly terms with Dennis Matsomi, and is the only person so far to use his first name.
