Draconis is encountered during the Baldur's Gate II: Throne of Bhaal and Baldur's Gate II: Enhanced Edition game versions.
Draconis is the spawn of Abazigal, one of The Five.
Draconis takes two forms in the game, Draconis (humanoid form) and later Draconis (dragon form).
He stands guard in front of Abazigal's Entrance, though he will also serve as the key to open that entrance.
He will hail the party upon sight and then attack.
