You shouldn't be so nitpicky about the details.

And in general, I completely agree with Draco regarding hiring angels, etc., and the analogies here can be drawn endlessly. The problem is (or rather, the good thing) that we don't see the actual process of angels appearing (how they are hired directly), but we each perceive it in our own way. Everyone has their own vision. This significantly enriches the world of Heroes, making it multifaceted and unlimited by any boundaries.
But that was slightly off-topic, and now back to the point.
The relationships between individuals (by which I mean all creatures, from heroes to seers in huts) develop in various ways. But the fact is, they exist. You don't have to look far for an example: Angels hate demons, Black Dragons hate Titans, Efreet hate Djinns, and vice versa. These are still some kind of relationships.
It's a little harder to trace the relationships between heroes, but they exist, and that's also a fact. Take, for example, Catherine and Roland.
Here, it should be noted that if the relationships between creatures (not heroes) should be attributed to the game mechanics, then the relationships between heroes should be attributed to the storyline
