Briar Brightline is a character in the Armour Astir game. His playbook is the Captain. A member of the group Horizon and the captain of the Constellation Class ship The Ivory Prince (also known as the Hellebore), he leads the mission to the Dyson Sphere at the galactic core, in order to prevent the power source that had been built there from falling into the hands of the Divine Principality.
Brightline wears a white and gold military jacket with huge epaulettes and a long tail. His captain's hat is a mood hat. This hat works about as well as current mood rings: it doesn't.
