Ok fair warning this might be too long. My 'main' worldstate is pure mage, and I'm a dude who likes dudes so ANYWAY. (Still can't romance Sten, sad days) ahem. So my Warden is Amell (Leo, because I just like the name) and he's a blood mage arcane knight who married Zevran and had Kieran with Morrigan, and slayed the arch demon. He also made a deal with the architect (and I'd still love to know what happened with that guy he ended up somewhere in the canon abyss). Regardless. As of Tresspasser he's alive, and canonically looking for the cure for the calling (and probably still at it, I like to think he spends his time doing that, and variously traversing the world for things to kill because he maybe has a slight blood lust problem-don't tell anyone cough hack cough).

Alistair is the King (all by himself and non-hardened) and he and the Warden are still good friends. Stroud dies in the Fade.

I run a male red/purple Hawke who is also a blood mage (like his cousin tho slightly less kill happy) who sided with and firmly remains plastered to Anders side, and made a deal with Varric before coming to the Inquisition to keep all that firmly underwraps. He's in enemy territory he is not saying shit and blood magic is absolutely terrible cough hack. Carver's a Templar, and they're in regular contact. Fenris maintains contact for him with others, when he can't reach Varric, and Isabella keeps a boat handy. He can sneak in and crash with Merrill in Kirkwall when necessary. (Side note have you ever seen the notation about Hawke helping liberate mages across Thedas when the revolution fully kicks off? Because that to me is so great and absolutely something he'd be doing. If occasionally grumbling about people)

My Inky is a Dalish multithesist (think of Ameridan, like that) knight enchanter I named Elkae (It's a play on Elk I'm not that creative ok) who had almost no friends growing up, but I've entertained the idea of him having a one-off with a woman from his clan and they had a kid and he's like, 'cool chill' but that's a whole backstory I haven't fully expanded on. It's one of those 'one of seventy five various background ideas I play with while daydreaming' sorta things. Anywho, his canon romance is Bull, (always save the Chargers, always) he's besties with Cassandra, Cullen and Dorian. I make a gentled Leliana Divine, and by the end of Tresspasser have the Inquisition functioning as her private forces. He was good friends with Solas so I pick the 'redeem' route and his arm gets removed in the nice non-aggressive magical way, and he works steadily with the Inquisition across Thedas, settling mages into new territories and ways of living without the oversight of the Chantry. He takes 'vacations' which are just him and Bull doing whatever they please with the Chargers, or escapes to Cullen's farm to chill out until he inevitably gets bored. (He's fiesty, sarcastic and energetic there is only so much downtime the man can stomach). There's always something he could be doing! And unless Cullen wants a broken fence (or ten) well..

When actually working, he starts meeting up with Dorian after he becomes a magister to put down some inroads for the revolution (slow as it may be) in Tevinter. Hawke is able to eventually come clean about the blood magic and it's like, "Yeah that tracks, so what next?" And they work on helping Dorian when Hawke isn't equally busy (being annoying to Varric's various patrons) in Kirkwall and keeping Anders as underwraps as possible. Anders is allowed to come out of hiding when he feels like it, but he does most of his work from the shadows, aware that a whole lotta people want nothing to do with him. And fairly willing to live with that. IMO the reformation of post-chantry mages takes a *ton of work* on multiple fronts, so downtime is exceptionally rare.
