A slight tremor in the ground and a wave running through the underworld energy soon after were the first signs Zach, Dukiel, Nessa, Anerias, Violina, and their herd of conspicuous familiars got.
The tremor was nothing like the violent ones that shook the ground like it was a punching bag earlier. It was gentle. It was the same with the gust. It was like someone had flapped a large fan on the other end of the tunnel or gently tapped the worm of smoky underworld energy filling the tunnel.
Neither of that had happened, though. Zach and the others knew that what Maer had warned them about was the cause for both the tremor and the wave of air.
They didn't stop moving. At this point, all they could do was live or die with their choice.
Another tremor came after a couple of seconds. Then, a gust again. Then, complete silence and stillness for more than a minute.
