Caleb Widogast

Caleb Widogast, born Bren Aldric Ermendrud, is a human wizard and a member of the adventuring party known as the Mighty Nein. He is played by Liam O'Brien.

Caleb is reserved, not wanting to draw too much attention to himself or his companion Nott. He showed little interest in the secrets of people besides Nott, hoping to avoid answering questions about himself. Caleb's generally dour and isolated manner morphs into an open and jubilant mood upon purchasing new books. He does not consider himself to be remotely brave.

Caleb possesses a deep self-loathing due to the circumstances of his parents' death. He believed that he was fully responsible despite being magically beguiled and the reassurances of both Nott and Beauregard that he was not to blame; he neither wanted nor accepted their consolations. He originally appeared to want revenge against Trent Ikithon; however, his present goal seems to be to prevent any more children being recruited and trained as he was.
