So in other words...Seraphims are susceptible to malevolence, so they form pacts with humans and that can protect them from being corrupted. And in exchange, a human with a pact can use the power of a seraphim to purify malevolence - and that's what makes a Shepherd. Meanwhile the domain is just an extensive aura of someone's strength.

Is that right?
