The city had more than Scalqa. Humans, Thilku, Ef'i, and even a few Fuveall witnessed the announcement and couldn't help but grow excited. Khan's cry didn't only ignore language barriers. It also conveyed his mindset, turning it into a quasi-poison that tainted the encampment's symphony and resonated with the people it touched.
The Fuveall were a rational bunch, so they quickly calmed down and became wary of Khan's strange ability to influence their hearts. However, the humans lingered on that inspiring cry, and some cursed the fact that they couldn't join Khan's mission.
As for the Thilku and Ef'i, they had it worse than the Scalqa. The various screens across the city had translated Khan's speech, and his clicking cry had delivered the final blow, almost prompting them to swear loyalty to him and join the imminent battle.
