By emphasizing Arcane Fate as a penalty more, and having fated Sidereals tend to live on Creation more until Exaltation instead of being raised by the Bureau, they allow greater diversity in Sidereals, while also having this tragic curse that pushes the Fellowship to be a Fellowship. You're having a work lunch with someone who believes the most insane religious heresies and is going steady with the God of Unfaithful Lovers as you debate a destiny about which city is going to be attacked by a warlord... and you have every reason to try to push past these problems and try to be collegial.
I've only been in one Sid game, but that circle had what I thought was an interesting dynamic; We had history together and had done work together in the past. We enjoyed working together, so we did it.
But we weren't like a tight-knit adventuring party like you might find in D&D or a Solar/Abyssal game; we were coworkers in the same convention. We had our own agendas, working towards similar goals. We spent a lot of time apart and split up. We brought other sids onto our missions, and while the four of us were the primary group, there were other sids. Even within the group we had our own individual dynamics; my Oracle and our Shieldbearer were making regular contact with the Walker in Darkness and the Underworld to try and gather information, which the others weren't aware of the full details of. My Oracle had a project with Kejak's rival whose name escapes me to fracture Skullstone's culture. My Oracle had a spat that cost the shieldbearer political influence. In our very first scene we co-signed a proposal to send a hurricane to destroy a city in An-Teng.
Hell, I set the Reckoner up on a blind date once.
It did feel like a fellowship. Our interests were kind of aligned towards the same end goal - the preservation of Creation (and in this game's case, the Convention on the Dead) but our interests and methods varied on a global scale.
Add all this to Omicron's "it might actually be healthier to hit it off with that boy from the theatre district for a brief passionate fling" and you can come to the conclusion that the healthiest and most equal relationships a Sidereal can pursue are going to be with the enemies of Creation.
"She's an enemy of life itself, a destroyer of all we hold dear!"
"Okay, I hear you. Counterpoint: She's
really hot."
It always struck me that the way Arcane Fate is portrayed in 3e seemed like it would subtlety but inevitably encourage reaching across enemy lines to the Getimians and vice versa, as while they come at it from very different angles, "the other side" is made up of some of the very few people in the world who could possibly understand the pain of being severed from every bond you had, of living in a world that does not recall you ever existing.
This would be true except that Getimians are, by their very nature, working
against fate and its plans. Still, Sid/Get collabs could be very fun.
I am looking forward to Getimians in 3e so much.
Healthy relationships? Nah time to work out a messy romance between a Sidereal and Infernal. All my brain electrons are in place and working max over drive, brain currently spitting smoke out of my ears.
Or you could date your Heaven's Dragon employee. There's absolutely
no toxic implications or unhealthy power dynamics in that whatsoever
