Well well, this was really interesting, wasn't it? Even from her pack she could hear the call and quickly made her way to the battlefield. She didn't remember if she had met this man or not, but that was no matter, he was challenging for a pack. He didn't look like much, but it took something... big to impress Esti. Still, she was curious as to how it would all work out. Cascade seemed to know him well enough. Sin Armada? Esti wondered if his parents named him that or if it was a self claimed name. Either way, it was kind of hilarious to her.
Esti walked up somewhat close to Cas, shooting her a side glance and a crooked smile, "Friend of yours?" she asked, her tone amused. The titan woman wondered how or even if this would effect Imperium. Threar surely never had before, so if it fell to this Sin, maybe things would change. Esti hummed to herself slightly as she mulled over the thoughts, wondering if Valentine would show up as well. It was certainly something to mention to him if he didn't, though Esti figured Cascade had him covered.
There were other wolves, but Esti paid little mind to them. It had been a long time since she had seen a pack challenge. It had been since Erani and Valhalla. Man, so much had changed in that time, and here they were again, at the battlefield watching two wolves fight over some land and some piss borders. It was strange to think about that way. Esti needed to know more of this Sin and his plans before she could pass any more judgement. For now, this was simply an entertaining show.
