The next day, Farah had already left for the imperial city on Damien's orders. Even though she hated being ordered around, she had no choice but to leave to get the Pandemonium Needles for Damien despite her mission being risky enough.
Damien knew keeping Farah alive was dangerous since a woman like her could soon find ways to circumvent the measures he had taken to stop her from betraying him.
However, he badly needed the Pandemonium Needles and also wanted to keep himself updated with what the Gale Emperor was up to.
This was a gamble he felt like he had to take to fulfill his own agendas.
