Some Absolutely Random Alistair Things: Royalty Edition.
You will have to literally physically wrestle him into anything fancy. He just wont have it. Nothing more elaborate than leathers, furs and simple weave cloth. He magically vanishes at the first sign of Formality.
Alistair has no sense of diplomacy and doesn't feel the need to play silly games with words. He will tell you exactly and directly how he feels about a situation and what his opinions are on any given matter. There is no posturing and double talk.
Initially leans heavily on Teagan for guidance and support. This reliance steadily weakens as he gains confidence and eventually Teagan is barely ever in Denerim letting his sort-of-nephew get on with things in his own unique way.
There are three crowns. One for daily wear when seated ( slouched and bored ) in the Great Hall as nobles have their audience with the King ( and Queen conditional ) where they come before him with their problems, grievances and complaints. One slightly more ornate one for more formal occasions such as banquets, galas and dinners / meetings with dignitaries from other counties. And then there is The Official Crown ( along with the scepter, orb and fur lined mantle ) only worn at coronations and other official ceremonies of state. He doesn't care for any of them.
Alistair has a small personal guard of trusted men and women and can often be found among them ( either sparring or drinking ) as he wont ask anyone to protect the Fereldan Royalty if he can't stand beside them.
He isn't into hunting, a hobby that would normally be considered appropriate for a Ferelden King but he does make sure the royal forests and areas around the city are maintained and protected.
He continues his interest in the arcane and collects magical/possessed artifacts… mostly to keep them away from anyone who would misuse them. There is a whole room full of these things on display to both keep them safe and for their arcane advisors to study.
Never stops collecting ornately carved figurines. He is a small boy inside.
Helps re-establish the Warden Compound in Denerim and builds up a massive library of Grey Warden Lore and History second only to that at Weishaupt.
Travels across Ferelden overseeing her restoration after the Blight. He is happier away from court among what the nobility would considerl "the ordinary. common" people. To him they are Ferelden.
Is in tentative negotiations with Orlais but can't be manipulated by the Empress.
Makes every effort to never be anything like either Cailan or Maric. This extends to his private relationships. Does not engage in affairs and dalliances.
There are those who insist he is an usurper or put on the throne as some Grey Warden bid for control or power. While not wanting to risk a civil war, he will not tolerate unrest. He knows from history that these things cannot always be solved without bloodshed and will fight those who threatens Ferelden's peace. But not 'at all costs' there are some prices that are just too high and if a compromise can be met he will take it. Many would call him idealistic and they might be correct but those who understand him refer to him as incorruptible. A king is to serve and this is something he doesn't want to forget.
it is the fact that he never wanted to be king, never wanted the power or status and this is what makes him a good king though. He does. however accept the responsibility reluctantly but not half-heartedly. Can he make those impossible often morally questionable or outright callous decisions? That remains to be seen.
Can sometimes be found up into the early hours of the morning studying politics, law, history and anything that could be useful. This is not common knowledge and many still see him as flippant and ignorant but there is power in being underestimated so he leans into that perception.
In 9:38 he travels to Antiva following a lead to where he might find Maric and returns fully committed to being good king. Whatever that means. But he will endeavor to find out. He doesn't talk about that journey.
There is always that restless part of him that would give all this up in an instant. Theirin blood or not.
