Heldyssa Shadowfall is a gnome Magister of the College Arcanum active in Arkrist during the late 88th century SE. As a Magister, she was a full professional member of the College rather than a student or Initiate, and she became involved in events surrounding the disappearances and hidden cult activity uncovered beneath the city in 8793 SE.
Heldyssa was among those rescued during the investigation that exposed The Voiceless. She later worked closely with Lucious as investigations beneath College-controlled property revealed ancient draconic structures connected with the deeper Arkrist Undercity. Those discoveries helped establish that the College’s modern facilities occupied only part of a much older complex whose original extent and purpose remained poorly understood.
