I'd like to note that, while not required, it should be extremely hard, if not impossible, for a mage to use more than one style at once. Otherwise it opens the field to powergaming of a nasty type. Perhaps the shape of the energy used in each style interferes with that of the others, or some similar reason.
Ooo, pilgrimages! I like the vibe of this one. The little story snippets are a good touch, for when your PCs are wondering, "Why the heck do we have to stop here on this pilgrimage?" And in each, there's something still there that can be involved in a subplot.
I like how this one turned out. The character makes good, solid sense. His capabilities match his backstory, and so do his flaws. I especially appreciate that he's not an idiot, and recognizes the treachery of Azoxul.
Overall, a rather effective cult leader.
The purposeful-yet-aimless drifting makes this the perfect recurring villain. PCs won't be able to take him down the first few times they encounter him, and by the later ones they'll start to realize that he's got much more up his sleeve than they bargained for.
