Aggrevius

Aggrevius is the name of a forgotten black dragon. Aggrevius lurks in the swamp behind the forest that surround the Haunted Courtyard. Aggrevius is not aggressive. Aggrevius used to be the king of the Haunted Courtyard, he says, but the Wrathful Werewolf, in greed of power, defeated him, and banished him to the swamp. The Wrathful Werewolf is the new king of the Haunted Courtyard. Aggrevius is the second most powerful creature in the Haunted Courtyard (not including the Wrathful Werewolf). The most powerful creature in the Haunted Courtyard (again, not including the Wrathful Werewolf) is Destronoir. If you defeat Aggrevius, then he will help you defeat the Wrathful Werewolf.
