Greyst Denali was a wise and calm Gen'dai Twilight Templar who was a close personal friend and mentor of Dade Leviathan. Like many of his race, he was a non-aggressive being, and was quite calm and kind, despite people thinking otherwise because of his hulking appearance. When the need arose, however, he was one of the most powerful warriors that the Templars had at their disposal. Despite his hulking appearance, however, he was extremely agile, and was the Vornskr Master of the Fire Warriors for 1,482 years until his supposed death in 1382 ABY.
