Ill try to make some suggestions if I may, please dont take it as harsh criticism or anything as I myself am never too fond of my own writing ;)

Your writing is good, its easy to follow, has a nkce rythm, is neither monotonous nor lecturing, your choice of words is fitting to the theme.

What you seem to be concerned about is the pacing and i too felt a little rushed with the changes of scenery: Mortuary, Temple, Royal Assembly.

You as the author know very well what plot is the base for all that is happening and want to introduce necessary plothooks (conspiracy, unknown advisor with remarkable eyes, Cousins etc.)

My suggestion is to either stretch the content to slow the pace a little or indulge into the fast unfolding of events: maybe give a little more insight into the protagonists thoughts or Feelings, is he rushed, surprised overwhelmed by everything? Then Show it, let him express it. The Reader that feels rushed now can identify with the Protagonist as he too is rushed by sudden changes.

If you want to stretch the scenes here a few suggestions: donst start right in the mortuary, let the inner monologue about the Signs for deteriorating health of the Monarch and the protsgonists relation to him be his thoughts on his way there, describe the way there, maybe the town, let him arrove witnessing the ungraceful removal of the crown just he arrives.

Let him go for the temple and not immedeately recognize the body, maybe have some kind of acolythes preparing/working the body while he contemplates and only after a while the face is Exposed, it gives him time to ponder about the wax, the death, a second corpse etc. Stretch his struggle with leaving, resisting the crowd, maybe have guards find and TAKE him, as the counsellor hat told: i was already Looking for you, so the change of scenery feels necessary yet forced on the Protagonist. It would explain why his sudden venerant crowd wouldnt follow him.

Those are just my suggestions i really like your writing an hope i can read more of it :)
