The most silent and withdrawn of the Lord Masters, Arminius Corelsti wields an incredible amount of power from the shadows. Master of the spirit hunter ranks, Arminius is also trusted as Rekin's closest advisor, due to his innate abilities of prescience (foresight), and his ability to "read" everything about a person of object simply by laying a hand upon them.
Note: Arminius Corelsti is the only completely blind spirit hunter. He was born as such, and has nver seen anything in the physical world.
