The mission

 Arielle almost complained after the guards told the Luna wants her to join her in the gold room but she was fascinated by the name of the room. 'Gold room huh? Tch! This human Luna is quite troublesome I can't wait to meet her and violate the oath I swore! ' she said excitedly in her head.

 Yes, she also came with a mission. From Brian's careful guidance, she knew that Elias was trying to make her do something that would give him a just reason to start a war but then what he didn't know was that blue moon pack also had a just reason to start a war as well. The massive amounts of rogue* wolves that attacked their pack suddenly was uncastrated by Elias, but they didn't have evidence.

 Arielle came here not only to discuss a peace treaty but to get that evidence. If Elias thinks he can pit her into war, she will show him that she still has one trick up her sleeve that would not result in war but blue moon pack will be victorious.
