The explosion of the dark orb was the final stage in their battle, as it not only inflicted mortal wounds on August but also helped Ern, Erza, and Alas deal with the other Elves, so the camp was already destroyed.
After defeating August, Wain received the final key.
[Wrath Key (Unique)
This key was received only by the one who was able to pass a special test and show his wrath. It is the road to the most powerful Spirit in history.]
Whoooooosh.
The rest of the keys shone brightly as they flew towards each other and formed a circle.
[Received Title - Key Collector]
[You have collected all seven keys, so now you can enter the Great Tree. The passageway will be open to all, but you will have a special bonus. You will feel the way to the Royal Spirit, while others will be in the unknown]
