you can't offer your poison to me
in your kingdom of filth

He does not trust this land. 

To be fair, Wrath trusts nobody and nothing. Kratos is the only exception, and he guards the royal prince with his life. It is more than being duty or honor bound to the young warrior, for he has come to care for the proud and cunning soul beneath his tutelage. There are no gods that he will ever trust, and few mortals on his list. His band of brothers had been an intermediate, a halfway point of trust. You don't love in the Rift. You procreate perhaps only because you have a dormant hope that the next generation can free you of your bonds. Or in Kratos' case, and many like him, they are born purely to satisfy the ephemeral politics that make a mockery of themselves throughout the land. For there are no kings or queens in the Rift, only those who play at importance while ignoring how they are shackled to the celestial slave-drivers they pretend to worship. 

There is no order, only organized chaos. 

At last they have an opportunity, however. The chance to free their people, so long as they can discover the knowledge of this land. Find a way back to the Rift to share the wisdom, to bring the false gods down from their thrones to beg for mercy at the feet of those they oppressed. Wrath will not grant it to them. He will kill them without question, without doubt or hesitation. They took everything from him, and he still wears their curse upon his hide and inside his body. In all the eons they spent ruling the Rift, they never showed mercy or compassion. He would not allow any of the denizens to speak in their defense. They would be liberated, and Wrath would make sure of that. 

Until then, they are left at the most profound disadvantage Wrath has ever found himself. Quite an accomplishment, all things considered. They are in a land they do not know, disoriented and lost, with no direction and no others but those who happen to come from the Rift as well. Wrath does not fool himself into believing that he and Kratos will find kinship in them. In the Rift you live for yourself, and bonds are few and precious in their evanescent nature. Just because they hail from the same place does not make them allies, and so he ushers Kratos away with a single-minded mission. Find someone willing to give them answers and direction, who would not be liable to try and attack them. Regroup. Cross the land with hopeful directions from whoever they find, and start building up a base of knowledge. Keep to the shadows, because this brightly lit world held too much fragile hope for someone as jaded as he.
