I'm a little uncertain while designing my character, how powerful exarches are supposed to be. Could you give an example of the kind of thing within their power, and an example for the kind of thing they can't do?
Also, are heroes just muggles with good gear?
As for the power of an Archon, I have been thinking a long time about how best to describe how powerful they are. So I'll use a mix of feats combined with comparisons with familiar characters from media, sticking to the realm of fantasy. Now a good starting place for Archons is to realize is they are far more than really powerful archmages. To say their demigods comes closest to the mark but might still come short considering this would conjure images of Greek demigods who are pretty damn tame in comparison. Now when talking about power, I'll like to draw the distinction between destructive power and raw potential power.
I may as well cover all the different types here and scale up.
Heroes. They are indeed just normal folks by all accounts. Kind of like fantasy batman, just normal dudes with good gear and training/upbringing. Capable of taking on a group of trained fighters on their own.
Exarchs would have the potential to take out a regiment on their own depending on their chosen schools of magic. A single Exarch would be worth 100 men, still, this is not universal as every Exarch will have different expertise. Something along the lines of the Dragonborn from Skyrim with full levels.
Archons -- If I was going to make an example of an Archon of full destructive power, let's say an Archon of Stone. In a region with high winds of creation, he'd be able to level a small city. Malekith, the Witch King from Warhammer, would be a good example. As for what they Can't do is that they are universally limited by the magic available in the region they are in. It often also comes down to the kind of magic they use. Since while all Archons possess magical powers, there is no other common thread between these women and men. An Archon might be made of fire, capable of conjuring storms, or able to heal with a touch - the only defining trait of an Archon is that this magic power originates from within.
The Archon of Shadow I'll use as an RP example. His power revolves around shadow and illusion magic. His main ability is his power to shadow walk, which is moving from one shadow to the next. He can even do this over long distances. As long as he has a perfect mental image of that place. So places he has visited numerous times. Beyond that his destructive ability is no more than mere heroes. However, his potential is incredibly dangerous.
In all, the extreme flexibility of idea's makes an exact power scaling difficult. But hopefully, my examples shed light on it.
Same, though I have no plans to give my character any powers beyond access to some magical artifacts. Perhaps he isn't powerful enough to be an exarch as a feudal lord piecing back together the shattered lands of the northern kingdom once ruled by his family? It's not terribly clear.
So a normal lord, or someone who just relies on mundane skill alone? An Exarch need not know any magic and can instead be an incredibly skilled warrior. If not I suppose he would just be average Hero type instead, but he'd not qualify to be the next Pontiff.
