Kalkstein Grimsbane

Kalkstein Grimsbane, referred to as  'the Demon Raven', is the Spymaster of the Sang-Lothor Imperium, member of the Golden Council, and estranged adoptive brother of Savina Grimsbane. "Creep above all else. Alleged predator." According to Cere Aizlewood, he is an enigmatic man whose origins and relation to Savina is still not fully understood. Kalkstein controls the Centurions, an elite royal force of House Lothlorian in the capital's palace of the Imperium, as well as a suspected blood mage, making him a very dangerous foe for the the Weastern Pirates.

Kalkstein met his end during the Imperial Wedding of 1490, after making an enemy of the Weastern Pirates.
