Brigade General Yulia told you to go to the Inggison Outpost and speak with Veille there. Veille, Kaisinel's agent, told you that it was time to attack Silentera Canyon, and that you should see Centurion Iaetia for your next mission. Iaetia had prepared the attack on Balaurea from the Illusion Fortress, but difficulties arose. Iaetia said she had discovered a secret corridor into Silentera Canyon that would decide the outcome of the battle. She asked you to secure the entrance, which would be used for the advance on Gelkmaros. You inspected the situation at Angrief Gate as Iaetia requested, and defeated the Balaur there. Then you destroyed the gate's control mechanism and in so doing secured the entrance for the Elyos at the Inggison Outpost.
