Kenku

Right after the Endless War of Agression the Kenku were actually a different nation of Aaracockra in the Southern Cliffs. There isnt much recorded history of them but scholars and wizards have concluded they were after an artifact of an Ancient. The artifact is known as the Wings of Grimm and was thought to be able to fly so fast you go in between dimensions. Theoretically you could even cross the line between Life and Death or Past and Future. Regardless of the Artifact,w hatever they did cursed the entire nation under the rule of Alvid the Grand, rendering them flightles and unable to speak their own voice. They went to the Aaracockra in the mountains for help bu t the Northern Clans feared what would happen should they help the Kenku and denied them help. Now the Hanging Kingdom of the Southern Cliffs is deserted and the rest of the Kenku have gone into the Woods of Jira.
