Not to be confused with Joseph.

Josef was a follower of Agrith-Naar in the Shadow of the Storm quest, and was one of the dark wizards recruited by Denath to summon the demon. He was curious about the ritual, wanting to learn more, so he read the demonic tome and, realising what the ritual actually was, stole the tome and hid it in the ruined kilns around Uzer. Denath killed him shortly afterwards.

He was friendly with Matthew, another dark wizard recruited for the ritual. Matthew was the only wizard in the ritual who actually cared about Josef after he disappeared, the others believing he ran away due to cowardice.
