The Black Lake Sect were getting rather suspicious of Azaroth's relationship with Erica. They felt that it was an unusually close one.
To them, it seemed as though Erica was unusually excited and motivated to obey Azaroth. There could be a hint of romantic intent hidden that followed Azaroth. All of them agreed that Azaroth was an extremely handsome individual.
He was so damn gorgeous that a woman would try to think about gaining his favor when she saw him first. The more the elders considered this option, the more certain they became of it.
Azaroth was actually aware that these kinds of thoughts were circulating within these elders' heads. However, he didn't warn Erica or try to stop these rumors. They worked to his own benefit.
