Domain Trouble.
The brown trunk-like origin god attacked him without warning. One of its stubby branches extended sharply towards him like a spear. He was prepared for it so he retaliated with his domain. Warning bells rang through their minds as soon as he initiated the summoning of his domain. They can sense, even before it was deployed, that it is dangerous to them. It came to them as a surprise that anything that he could produce could threaten them. The least of their expectations is that his domain is a threat to them. But that didn't stop them from trying to run away.
The origin matrix warned them of the impending danger. It is a perk of being an Origin god with an actual origin and concept that is connected with the law matrix of the law universe. Their perception and intuition get a boost. But they failed to evade the danger despite getting advanced warnings of it. A domain is not something that can be dodged. It can only be resisted.
