Carefully prepared notes.
Note 1: "Tyranthraxus is definitely a produce of immersion in the Pool of Radiance. His extraordinary brilliance, vigor, charisma, and power of command must be a direct result of exposure to the effects of the Pool."
Note 2: "The Pool of Radiance may grant special magical abilities. Tyranthraxus exhibits a fiery aura, obviously magical. He also seems to have extraordinary means of obtaining information. Special magical powers granted by the pool would explain both the aura and the extra information gathering capability."Note 3. "Tyranthraxus tells stories about moving down from the north. Though he never mentions the Pool, I gather that it is northwest of the Dragonspine Mountains. Strangely, he occasionally lets slip that he is never far from the Pool, but that must be a parenthetical reference."
