An excellent question.  Pulling back a bit, we could even surmise about the basic nature of Magic.  For example, is Magic intrinsic?  If not, it it's some kind of alien, Magic might eventually pick up it's toys and leave.  If Magic is intrinsic, tied to Gaia, an emergent property of Human Consciousness, or some such, then as long as you have this kind of population growth, the eventual reveal of Magic was always going to happen, and perhaps that is what has happened in the Magic-rich Universes we know about, just earlier in their timelines.
Well, trying to say it was caused because he didn't know about Seers at all would be a start... Boss might point out that they should have planned for in case his plan was flawed or failed for some reason.  You know, I can see Edward being begged to come back.  That whole avoiding Apocalypse thing.
I am more concerned about the fallout for Tedd in this, especially because he is now on Arthur's radar.
As has been mentioned in other posts, Voltaire is frustrated by the limits on Immortals and wants them removed.  We can theorize that he wanted Magic changed severely to limit it's use by humans; I would think that if Tedd were traumatized and distrustful of Magic, he would have argued for limiting Magic.  I don't think Voltaire knew how many Seers there were either.
In the above scenario, if Voltaire argued for Immortals becoming more involved in human affairs, this would seem like a return to Immortals acting like the deities of old pantheons, and perhaps that is what happened in the past, giving rise to mythologies of Gods having direct contact with humans.  He could have argued that humans need guidance...
Ironically, in a world with Magic revealed, it would make more sense to lessen the limits on Immortals, but I can see why Voltaire wouldn't like this.  Immortals may be powerful, but imagine an Immortal with plans of Godhood going up against fully staffed and militarily trained regiments of Magicians prepared to face magical threats; as well it would difficult to impress people that you are a deity if everyone knows about Magic and the bestiary of magical creatures just by looking it up on Wikipedia.
Oh my gosh, youtube videos of DIY magic hacks; magic geeks publishing a magical-themed Make magazine featuring projects you can do with magic crossed with other tech disciplines!
Sorry, got distracted by the Happy Shininess of applying geekness to magic.
 

Then he should look for the disco!

Why not Mr. Pompoms?

In case anyone wasn't sure, this song is posted in all seriousness, rather than to be funny. I'm actually rather choked up over here.

Poor Adrian.  He's lived such along time, and his mother was the one constant, the one person who's been there the whole time.  Even when they weren't seeing each other, he knew she was out there.  He may even have wanted her to reset, although he never said anything to imply it.  And now, she's gone, and she's likely told him all about resets and that she'll basically forget him, that his mother will be gone if she resets.  He's an orphan now.
Which is basically what happens to every child who outlives their parents.  Even if they're eighty and their parent was a hundred.  Does multiplying those numbers by ten or twenty make any real difference?

If it turns out that I am a vampire, this is the way I wan to be destroyed.

So, another opportunity to dust off my old theory of Elliot and Magus getting stuck in the same body, in which case Dan would be obligated to bring in Terra to compete with Ashley and all the others with a thing for Elliot.
How about a castling spell? That is, an analog to the chess move where you shuffle the position of your king and a rook. Say, Diane switches places with Susan.
Or perhaps even more appropriately, a spell to summon Nanase.

I can't believe that Pandora hasn't given Diane a mark by this time. Maybe she can kill vampires by hugging them now.

But then there would be no wacky hijinks punctuated by sheer terror... sitcom vampire battles!

Susan already has four self-critical voices. Any more and she'll need a second head like Zaphod Beeblebrox.

Preparing for the next bad weather horror movie, set in Florida: Alligatornado.

The Burmese Pythons multiplying in Florida swamps are getting big enough to eat alligators. So, get ready for Pythoon.

He might have expected a possible need to pay it. I still don't think he cared.

If you don't, I won't either.

Shoot him now! Shoot him now!!

Wow, upgraded Fairy Summon Spell allowing for custom fairies.  Now I am imagining little Nase with a sword and armor, little Susan swinging double hammers, and muscle-y little Grace ready to punch someone out.

Well, wait for Susan to go through some upgrades to her spell, and perhaps she'll get closer to Mjolnir. 
Argh, a smart villain.  Yeah, he was definitely already shaping up to be the one to watch out for.  He seems to have opted for a more low key aspect of Aberration-hood, and also seems more concerned with tactics and evaluating his enemy.  I am concerned as to how his monsterness will manifest, given how calmly he threatened the big beast aberration.  He is disdainful of fancy magic; he could have something more straightforward but potentially very dangerous, stealth and speed for example.

Why? It's easier to conjure another than to catch the one returning back.
Well, he DID hoped they will actually kill Adrian ... but he likes his money and might not believe vampires will be able to work together effectively anyway.
As if anybody would try to interrogate vampire.
Probably at least three centuries. I think Pandora is sure she taught him everything she can.

Now this is just... wow.  I know it's a tense situation and Susan is in real danger, but come on, a koala vampire with a little hat?  He's not cute but he is.  I don't know; makes me want to hug him with a wooden stake.  I mean he and the bearded snake vampire are halfway to a muppet band.

Noooo, not him! I want him to stay safe and happy where he won't get hurt! >.<

Catalina is a Spanish or Porguguese version of Katherine, meaning "pure". Maybe Dan will do something with that connection someday. "Rhoda" means "rose"; it's from Greek (but also was a very popular Latin name, yet another thing the Romans stole for themselves. It can also refer to a person from Rhodes, which is named for its famous rosees. And ancestors from the Eastern Mediterranean sort of fit with Rhoda's complexion.

I like the theory about it being Jerry. The narration comes across like observations he would have made during and after Susan's awakening and then passed along to Zeus.

That explains the Colossus. They clearly cheated. It started out much smaller and then one of Rhoda's ancestors supersized it.

Dragons, oh my.  That is a fine can of wyrms.  Warning, I am going to go off into a long and rambling, but hopefully polite, rant.
Many fantasy writer of European style dragons trace their lineage from Beowulf's Final Battle with the Dragon, which was quite a beast and introduced fire-breathing and horde of gold to the pot.  Have you seen the classic St. George and the Dragon?  It seems like such a small wyrm compared to the Smaug of the Hobbit, but of course, size is not so much an issue; the thing was deadly poisonous and from the legend, threatened to poison the lake if not appeased.  Or the Lambton Worm (Dragon) that the Lair of the White Worm was based on?  It kept reattaching pieces of itself that were cut off, making it ever so difficult to kill.  The real danger, was that once given the way to kill it, the hero had to kill the first thing he saw after dispatching the worm or have his family cursed.  That didn't work out so well.
On the other hand, the eastern dragons are hard to match for power, being more deities with control over water and weather, but they are thought of as symbols of prosperity and good luck, not evil princess-stealers.  And do Mesoamerican Feathered Serpent deities count?  Or the Philippine's Bakunawa that causes eclipses?  Or the Great Horned Serpent of many Native American tribes (this one was so poisonous, the tiniest bit of breath would kill any creature, and to even see one sleeping would bring death to the hunter's family.  Ouch.)
The varieties are amazing and wonderful and I love that about mythology and fantasy.  The problem can arise when you start comparing them.  It's like my son talking up One Punch Man as so overpowered that he could take on Superman.  The point, I tell him, is not how powerful each is, but in their universe, how interesting are the stories?  My daughter was running a game without rules, and was allowing any type of character.  My son wanted to be a Primordial Being of Knowledge.  She asked me if that was more powerful than a God of Knowledge.  Hoo boy.  I riffed off an answer (Primordial Being know things outside of the universe that can cause madness and can change the rules of the universe but a God of Knowledge knows rules that can bind the Primordial Being.  Now, who gets initiative.)  I then gave her ways to have such a character but keep it balanced in a role-playing group of beings of mixed power levels (for example, have it trapped in the body of a little girl and most of the power kept in check except in the presence of certain kinds of danger, i.e. the-younger-and-more-helpless-the-more-powerful-it-is trope, not sure what the real name is).
Bottomline, the Moperverse has a certain power level, and Dan tries to keep certain balance.  The bulldog dragon was challenging and dangerous to the protagonists.  It worked well in the story.  Sucess!

I noticed that.  I figured it was part of her upgraded sword summons, the glowing one she unintentionally showed Ellen and Nanase, but then I started to wonder, is that a new spell or do spells upgrade and reveal new parts?
Also, is it just me, or is the first panel really disturbing.  I mean, I have seen more graphic stuff in comics/graphic novels and I am not usually squeamish, but there is something about the person running crying, she/he looks so much like Catalina, and the emotion is so visceral.  This person fears for their life, and the silly looking vampire might actually kill this person, bonus be danged.  Despite how silly the vampire looks, this scene really got to me emotionally; I felt horrified.  Perhaps its also how ... nice... the Moperverse usually seems to be, as well.  So of course I can imagine Susan's rage at this intrusion of horror into her world and her cleaving the monster was very satisfying.
Bottom line, very effective, but I am glad that something like this is usually not the norm.
