Adrian once asked the Daemos Elders why they are not hunting down the Primordial Beasts when they can deal large amounts of damage and death. The answer that the Daemos Elders actually shocked him because he did not expect it. It seems that the Primordial Beasts were also part of the deal of non-aggression pact.
The Daemos usually left the Primordial Beasts alone because they are forces of nature and beings that are part of nature themselves. The only way for that non-aggression pact to not function is when a Primordial Beast becomes mad or lose their rationality that they destroy the world. The Daemos are given the heavy responsibility of maintaining the world barrier and touching it is already akin to nullification of the non-aggression pact.
