Character from Primal Hunter by Zogarth
A Primordial of shadows who blessed Caleb — the patron behind the Court of Shadows and one of the twelve who has been content to operate in darkness.
Umbra is the Primordial whose blessing powers Caleb's Court of Shadows. Unlike more ostentatious Primordials like the Malefic Viper or Valdemar, Umbra operates quietly — which is appropriate for a being associated with shadows and stealth. Umbra's presence in the story is felt through Caleb's abilities and the Court's capabilities rather than through direct appearances.
A being of shadow and concealment whose physical form, if it has one, is deliberately unknowable.
