Core Q&A Expanded Answer
The void and sight are forms of Tuatha Time Magic, not Druidic Elemental Magic. The void is associated with Near Time and can let a warrior perceive an opponent's intended move before the muscles react. Sight is associated with Future Time and is typically used by a Seer or Seeress to seek portents and foresee what might be. Warriors and Druids can access these abilities at varying levels of proficiency.
