Ethan was listening to the snake's plane, he had only met the protector once, yet he wasn't able to see whatever that creature was. He only saw a very strong light but his appearance was invisible. Also, the voice was unrecognizable, besides that he could still feel a strong presence coming from that light, whatever the protector was it must be a very powerful creature to emanate such a powerful aura without the need of revealing its appearance.
The snakes planned to affect all the animals and create an army, then they would bring all the animals affected to the supernatural creatures underworld, to help them to get free as many demons as possible and take control of the entire world as that happened in the past.
Despite the plan seemed very concerning, Ethan still doubted that was everything they were planing, he was sure there was more under the surface.
