I would assume the Archon is preparing an army of soldier/servants to do battle with another powerful entity.
One problem for the Archon may be that the nature of the battle and the ultimate battlefield may be unknown until the battle is joined.
Even the role of Karsh may be unknown in the battle.
I can see that the battle is not going to go well for the Archon, but it might turn into an opportunity for Karsh.
I can also see that the telling of this story might require six books.
*eyes go to pinpoints, D-sheare falls over*
Six?
The Archon, as you guessed is preparing a vast army.
Far more than he needs for the job, actually.
His goal, as it was ‘back when Karsh was a kid, is to wipe the Realm off the map.
And claim the thrones and crowns for himself in an odd belief of his that they will increase his power.
If I could do animation, I’d be tempted to try and animate the entire tale instead.
