Cockatrice
Mirror Alteon’s servant
The Cockatrice steals the Egg of Order and uses its gaze to force fallen paladins into its service. It boasts that serving Mirror Alteon earned it powers denied to other beasts. The Hero turns its gaze back on it with Drakath’s blade, and the Cockatrice is imprisoned after the egg is recovered.
