The Matriarch's Hidden Trump Card

Yale was still hidden in the crowd that had started moving towards the places where the disturbances were being provoked.

However, that crowd didn't manage to accomplish anything because everyone stopped to move a few seconds after they started to move.

"The more you move, the quicker the poison will spread on the body. If all of you remained on the spot, you might have lasted some more minutes."

Yale had poisoned all the crowd in the time he spent hidden among them. The effect of the poison was only putting them into a deep sleep, but without feeling a great pain or without Yale giving them the antidote, they wouldn't be able to awaken in a day.

The only bad part of that poison was that it could only affect those at the Elder Rank or lower.
