Primus Sha'aull

"If your enemy speaks with a blade, master the sword."

- Grimoire description

Primus Sha'aul is a Cabal Centurion fought at the end of The Garden's Spire. He is the Primus of the Blind Legion and has an interest in Vex artifacts. No one knows what fascination the machines held for Sha'aull, although he was reportedly putting his command at great risk by pushing into Vex territory. Sha'aull was assassinated however, after a Guardian breached the Legion's perimeter in order to investigate the Vex Conflux held by the Cabal.

Trivia

 * "Primus" appears to be a title or rank within the Cabal command structure, along with "Val", "Bracus" and "Valus".
 * Sha'aul was the first Primus to appear in Destiny.
 * In his Grimoire card, his armor color is black and yellow. Yet, in game, his armor color is white and yellow. This most likely is a developer oversight.
