That was a great day for the Academy - Margaret, our Alchemy Master, finally perfected her Liquid Gold Elixir formula, what an achievement! Lead to gold with just a few drops... take that Midas!

On a less positive note - once again I caught my apprentice, Catherine, burning her own Aether when practicing some powerful spell. This has to stop or she will cause a permanent damage to herself. I've asked Henry to talk to her. He was able to get through to me, hopefully he will be able to do the same for her.

Another boundary was pushed! Charles managed to fuse Water and Air elements with one enchanting spell to create an ice greatsword. And then he named it "Frostbite"... on Merlin's beard, one more pun from this guy, and I'm looking for a new Enchanting Master.

Also today, Catherine took off for home. She got troubling news that her sister has fallen ill, hopefully it's nothing serious.

Catherine left us for good... Shortly after she came back she demanded I hand over Soulstone to her. As it turned out, her sister is gravely ill and Catherine's plan was to split her own Aether in two, and infuse her sister with the second half. To even think of that is to defy our most fundamental principles. I didn't even had a chance to cast her out, as soon as it was clear she will not get the stone, she ran away shouting curses.

Today we were supposed to celebrate William and his great effort to summon Water and Fire spirits at once, but I don't think anyone will feel like celebrating any time soon...

Months of tracking movements of "the comet" finally bore fruit. I managed to precisely define the crash area and we were able to retrieve the meteorite before anyone else got any wiser. Element sensitive crystals are already growing on it and we will have a stable source of elemental gems in no time.

Catherine was recently seen in company of some commoner, known for his basic skills in Earth channeling and it seems they formed an alliance. There are rumors about them building an earth golem - pff! There is no chance a man of his origin possesses the skills necessary to animate a golem.

Nevertheless, I've sealed Soulstone and moved it to the top of our tower. I also asked Charles to put a protective Ice screen around it, just in case.

My Magnum Opus is finally completed - I've mastered temporary Aether multiplication and now I can be in a few places at once, I can even move our armors from the Dining Hall. Unfortunately Theresa got scared, I need to apologize immediately or we will be starving for a week, if not longer.

Wait! I can hear some shouting in the front... It's Catherine, she's back and she's not alone! They're storming the Academy with a dragon! We're doomed... oh, it's "just" a wyvern - we might live to see another day...

The build:

For the building I took inspiration mainly from Victorian style manors and added some Gothic and Romanesque accents. The main build consists of two open back buildings that can be placed back to back and create one fully closed model.

Academy building:

Outside: designed to resemble outside of a campus with benches, plants and a small fountain,
Alchemy Floor with Potions Room, corridor with displays, and Alchemy Master's workshop with Alembic table,
Elemental Floor with Enchanting Master's workshop, corridor with meteorite and displays, and Scrying Orb Room,
Top Floor, for Archmage use only with his office, pigeons cage and telescope.
Top of the tower is a hiding place for an enchanted box containing the Soulstone.
Since this is a place where most powerful mages of the realm live, there are no staircases, and they use portals instead.

Dormitory:

Outside: contains plants, wild ivy and flowers, and the first Archmage bust,
Dining Hall with a kitchen next to it,
From there you can climb the ladder to apprentices' living quarters,
Underneath, with entrance from the other side of the building is a bathroom with marble in-ground bath with magical taps,
Top floor is a study area with a dedicated library,
Top of the tower is hunted by a ghost.

Side builds:

Wyvern - bewitched, with transparent dark-pink accents to highlight the spell,
Golem - infused with Earth Element,
Spirits:

Fire Spirit, with a great battle hammer, giant shield and on eight legs to firmly stand its ground
Water Spirit, built to look like a fountain brought to life.
