After Shira left the Spire, she immediately flew to the south. She realized that she didn't have any time anymore. The Leader had said that Silva was already more powerful than her, and, for once, she believed him. It would only be a matter of time until Silva challenged her. After all, Silva was ready to take this risk for his Camp.
Like this, Shira left the Tribe, and she wouldn't return until she had killed three Lords. If she intended to start right now, she would have flown to the west. After all, they had a direct neighbor there. Yet, she wouldn't go there in her current condition. First, she had to wait for her head to regrow. That would probably take some hours.
A day later, Gravis gathered the whole Tribe and told them about his new program. The reactions were mixed. The Lords grew excited when they heard that. Initially, they had believed that there wasn't enough food for everyone. Yet, this solved the whole issue.
